| * nilfs2: support contiguous lookup of blocksRyusuke Konishi2009-06-10
| | | | | | | | | | | | | | | | | | | | | | | | Although get_block() callback function can return extent of contiguous blocks with bh->b_size, nilfs_get_block() function did not support this feature. This adds contiguous lookup feature to the block mapping codes of nilfs, and allows the nilfs_get_blocks() function to return the extent information by applying the feature.

| * nilfs2: add sync_page method to page caches of meta dataRyusuke Konishi2009-06-10
| | | | | | | | | | | | | | | | | | | | | | | | This applies block_sync_page() function to the sync_page method of page caches for meta data files, gc page caches, and btree node buffers. This is a companion patch of ("nilfs2: enable sync_page mothod") which applied the function for data pages. This allows lock_page() for those meta data to unplug pending bio requests.

| * nilfs2: use device's backing_dev_info for btree node cachesRyusuke Konishi2009-06-10
| | | | | | | | | | | | | | | | Previously, default_backing_dev_info was used for the mapping of btree node caches. This uses device dependent backing_dev_info to allow detailed control of the device for the btree node pages. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
| * nilfs2: return EBUSY against delete request on snapshotRyusuke Konishi2009-06-10
| | | | | | | | | | | | | | | | | | | | | | | | This helps userland programs like the rmcp command to distinguish error codes returned against a checkpoint removal request. Previously -EPERM was returned, and not discriminable from real permission errors. This also allows removal of the latest checkpoint because the deletion leads to create a new checkpoint, and thus it's harmless for the filesystem.

| * nilfs2: enable sync_page methodRyusuke Konishi2009-06-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a missing sync_page method which unplugs bio requests when waiting for page locks. This will improve read performance of nilfs. Here is a measurement result using dd command. Without this patch: # mount -t nilfs2 /dev/sde1 /test # dd if=/test/aaa of=/dev/null bs=512k 1024+0 records in 1024+0 records out 536870912 bytes (537 MB) copied, 6.00688 seconds, 89.4 MB/s With this patch: # mount -t nilfs2 /dev/sde1 /test # dd if=/test/aaa of=/dev/null bs=512k 1024+0 records in 1024+0 records out 536870912 bytes (537 MB) copied, 3.54998 seconds, 151 MB/s Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
| * nilfs2: set bio unplug flag for the last bio in segmentRyusuke Konishi2009-06-10
| | | | | | | | | | | | | | | | This sets BIO_RW_UNPLUG flag on the last bio of each segment during write. The last bio should be unplugged immediately because the caller waits for the completion after the submission. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
| * nilfs2: allow future expansion of metadata read out via get info ioctlRyusuke Konishi2009-06-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nilfs has some ioctl commands to read out metadata from meta data files: - NILFS_IOCTL_GET_CPINFO for checkpoint file, - NILFS_IOCTL_GET_SUINFO for segment usage file, and - NILFS_IOCTL_GET_VINFO for Disk Address Transalation (DAT) file, respectively. Every routine on these metadata files is implemented so that it allows future expansion of on-disk format. But, the above ioctl commands do not support expansion even though nilfs_argv structure can handle arbitrary size for data exchanged via ioctl. This allows future expansion of the following structures which give basic format of the "get information" ioctls: - struct nilfs_cpinfo - struct nilfs_suinfo - struct nilfs_vinfo So, this introduces forward compatility of such ioctl commands. In this patch, a sanity check in nilfs_ioctl_get_info() function is changed to accept larger data structure [1], and metadata read routines are rewritten so that they become compatible for larger structures; the routines will just ignore the remaining fields which the current version of nilfs doesn't know. [1] The ioctl function already has another upper limit (PAGE_SIZE against a structure, which appears in nilfs_ioctl_wrap_copy function), and this will not cause security problem.

| * NILFS2: Pagecache usage optimization on NILFS2Hisashi Hifumi2009-06-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hi, I introduced "is_partially_uptodate" aops for NILFS2. A page can have multiple buffers and even if a page is not uptodate, some buffers can be uptodate on pagesize != blocksize environment. This aops checks that all buffers which correspond to a part of a file that we want to read are uptodate. If so, we do not have to issue actual read IO to HDD even if a page is not uptodate because the portion we want to read are uptodate. "block_is_partially_uptodate" function is already used by ext2/3/4. With the following patch random read/write mixed workloads or random read after random write workloads can be optimized and we can get performance improvement. I did a performance test using the sysbench. 1 --file-block-size=8K --file-total-size=2G --file-test-mode=rndrw --file-fsync-freq=0 --fil e-rw-ratio=1 run -2.6.30-rc5 Test execution summary: total time: 151.2907s total number of events: 200000 total time taken by event execution: 2409.8387 per-request statistics: min: 0.0000s avg: 0.0120s max: 0.9306s approx. 95 percentile: 0.0439s Threads fairness: events (avg/stddev): 12500.0000/238.52 execution time (avg/stddev): 150.6149/0.01 -2.6.30-rc5-patched Test execution summary: total time: 140.8828s total number of events: 200000 total time taken by event execution: 2240.8577 per-request statistics: min: 0.0000s avg: 0.0112s max: 0.8750s approx. 95 percentile: 0.0418s Threads fairness: events (avg/stddev): 12500.0000/218.43 execution time (avg/stddev): 140.0536/0.01 arch: ia64 pagesize: 16k Thanks.

| * nilfs2: remove bmap pointer operationsRyusuke Konishi2009-06-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, the bmap codes of nilfs used three types of function tables. The abuse of indirect function calls decreased source readability and suffered many indirect jumps which would confuse branch prediction of processors. This eliminates one type of the function tables, nilfs_bmap_ptr_operations, which was used to dispatch low level pointer operations of the nilfs bmap. This adds a new integer variable "b_ptr_type" to nilfs_bmap struct, and uses the value to select the pointer operations. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
| * nilfs2: remove useless b_low and b_high fields from nilfs_bmap structRyusuke Konishi2009-06-10
| | | | | | | | | | | | | | | | | | | | | | This will cut off 16 bytes from the nilfs_bmap struct which is embedded in the on-memory inode of nilfs. The b_high field was never used, and the b_low field stores a constant value which can be determined by whether the inode uses btree for block mapping or not.

| * nilfs2: remove header file for segment list operationsRyusuke Konishi2009-06-10
| | | | | | | | | | | | | | | | | | | | | | This will eliminate obsolete list operations of nilfs_segment_entry structure which has been used to handle mutiple segment numbers. The patch ("nilfs2: remove list of freeing segments") removed use of the structure from the segment constructor code, and this patch simplifies the remaining code by integrating it into recovery.c.

| * nilfs2: eliminate removal list of segmentsRyusuke Konishi2009-06-10
| | | | | | | | | | | | | | | | | | | | | | | | This will clean up the removal list of segments and the related functions from segment.c and ioctl.c, which have hurt code readability. This elimination is applied by using nilfs_sufile_updatev() previously introduced in the patch ("nilfs2: add sufile function that can modify multiple segment usages").

* | ramfs: ignore unknown mount optionsMike Frysinger2009-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On systems where CONFIG_SHMEM is disabled, mounting tmpfs filesystems can fail when tmpfs options are used. This is because tmpfs creates a small wrapper around ramfs which rejects unknown options, and ramfs itself only supports a tiny subset of what tmpfs supports. This makes it pretty hard to use the same userspace systems across different configuration systems. As such, ramfs should ignore the tmpfs options when tmpfs is merely a wrapper around ramfs. This used to work before commit c3b1b1cbf0 as previously, ramfs would ignore all options. But now, we get: ramfs: bad mount option: size=10M mount: mounting mdev on /dev failed: Invalid argument Another option might be to restore the previous behavior, where ramfs simply ignored all unknown mount options ... which is what Hugh prefers.

A sample linker script is included to give the preferred order of the sections for the architectures that do not have any special requirments. These definitions are also a first step towards eventual support for -ffunction-sections. The definitions makes it much easier to do a global renaming of section names - but the main purpose is to clean up the linker scripts.

| * | menu: fix embedded menu presentationRandy Dunlap2009-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The STRIP_ASM_SYMS kconfig symbol mucks up the embedded menu because STRIP_ASM_SYMS is in the middle of the embedded menu items but it does not depend on EMBEDDED. Move it to beyond the end of the embedded menu so that the menu is presented correctly. Or if STRIP_ASM_SYMS should depend on EMBEDDED, that can also be fixed.

| * | scripts/headers_check.pl: correct RE in header CONFIG leak checkRobert P. J. Day2009-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Correct the regular expression in scripts/headers_check.pl to include '_' as a valid character in the class; otherwise, the check will report a "leaked" symbol of CONFIG_A_B_C as merely CONFIG_A. This patch will make no difference whatsoever in the current kernel tree as the call to the perl routine that does that check is currently commented out: &check_include(); &check_asm_types(); &check_sizetypes(); &check_prototypes(); # Dropped for now. Too much noise &check_config(); However, I noticed that problem when I was building the yum downloadable kernel source rpm for fedora 11 (beta), which *does* run that check, and that's where the problem became obvious.

| * | kconfig: do not hardcode "include/config/auto.conf" filenameMarkus Heidelberg2009-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Regardless of KCONFIG_AUTOCONFIG, the filename written as a Make target into "include/config/auto.conf.cmd" was always the default one. Of course this doesn't make it work for the Kernel kbuild system, since there the filename is hardcoded at several places in the Makefiles.

| * | kconfig: do not hardcode ".config" filenameMarkus Heidelberg2009-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than hardcoding ".config" use conf_get_configname(), which also respects the environment variable KCONFIG_CONFIG. This fixes "make silentoldconfig" when KCONFIG_CONFIG is used and also suggests the given filename for "Load" and "Save as" in qconf.
