* ext4: remove calls to ext4_jbd2_file_inode() from delalloc write pathTheodore Ts'o2012-11-15
| | | | | | | | | | | | The calls to ext4_jbd2_file_inode() are needed to guarantee that we do not expose stale data in the data=ordered mode. However, they are not necessary because in all of the cases where we have newly allocated blocks in the delayed allocation write path, we immediately submit the dirty pages for I/O. Hence, we can avoid the overhead of adding the inode to the list of inodes whose data pages will be to be flushed out to disk completely during the next commit operation.

* ext4: don't verify checksums of dx non-leaf nodes during fallback scanDarrick J. Wong2012-11-12
| | | | | | | | | | | | During a directory entry lookup of a hashed directory, if the hash-based lookup functions fail and we fall back to a linear scan, don't try to verify the dirent checksum on the internal nodes of the hash tree because they don't store a checksum in a hidden dirent like the leaf nodes do.

* ext4: do not use ext4_error() when there is no space in dir leaf for csumTheodore Ts'o2012-11-10
| | | | | | | | | | | If there is no space for a checksum in a directory leaf node, previously we would use EXT4_ERROR_INODE() which would mark the file system as inconsistent. While it would be nice to use e2fsck -D, it certainly isn't required, so just print a warning using ext4_warning(). Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Cc: "Darrick J.

* ext4: introduce lseek SEEK_DATA/SEEK_HOLE supportZheng Liu2012-11-08
| | | | | | | | | | | | | | | | | | | | | This patch makes ext4 really support SEEK_DATA/SEEK_HOLE flags. Block-mapped and extent-mapped files are fully implemented together because ext4_map_blocks hides this differences. After applying this patch, it will cause a failure in xfstest #285 when the file is block-mapped due to block-mapped file isn't support fallocate(2). I had tried to use ext4_ext_walk_space() to retrieve the offset for a extent-mapped file. But finally I decide to keep using ext4_map_blocks() to support SEEK_DATA/SEEK_HOLE because ext4_map_blocks() can hide the difference between block-mapped file and extent-mapped file. Moreover, in next step, extent status tree will track all extent status, and we can get all mappings from this tree. So I think that using ext4_map_blocks() is a better choice.

* ext4: fix error handling in ext4_fill_super()Lukas Czerner2012-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | There are some places in ext4_fill_super() where we would not return proper error code if something fails. The confusion is caused probably due to the fact that we have two "kind-of" return variables 'ret'and 'err'. 'ret' is used to return error code from ext4_fill_super() where err is used to store return values from other functions within ext4_fill_super(). However some places were missing the obligatory 'ret = err'. We could put the assignment where it is missing, but we can have better "future proof" solution. Or we could convert the code to use just one, but it would require more rewrites. This commit fixes the problem by returning value from 'err' variable if it is set and 'ret' otherwise in error handling branch of the ext4_fill_super(). The reasoning is that 'ret' value is often set to default "-EINVAL" or explicit value, where 'err' is used to store return value from other functions and should be otherwise zero. https://bugzilla.kernel.org/show_bug.cgi?id=48431 Signed-off-by: Lukas Czerner <lczerner@redhat.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

* jbd2: remove VLAIS usage from JBD2 codeBehan Webster2012-11-08

* ext4: fix unjournaled inode bitmap modificationEric Sandeen2012-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 119c0d4460b001e44b41dcf73dc6ee794b98bd31 changed ext4_new_inode() such that the inode bitmap was being modified outside a transaction, which could lead to corruption, and was discovered when journal_checksum found a bad checksum in the journal during log replay. Nix ran into this when using the journal_async_commit mount option, which enables journal checksumming. The ensuing journal replay failures due to the bad checksums led to filesystem corruption reported as the now infamous "Apparent serious progressive ext4 data corruption bug" [ Changed by tytso to only call ext4_journal_get_write_access() only when we're fairly certain that we're going to allocate the inode. ] I've tested this by mounting with journal_checksum and running fsstress then dropping power; I've also tested by hacking DM to create snapshots w/o first quiescing, which allows me to test journal replay repeatedly w/o actually power-cycling the box. Without the patch I hit a journal checksum error every time. With this fix it survives many iterations.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to decide if ktest should bother installing modules on the target box, it checks if the config file has CONFIG_MODULES=y. But it also checks if the '=y' part exists. It only will install modules if the config exists and is set with '=y'. But as the regex that was used tests: /^CONFIG_MODULES(=y)?/ this will also match: CONFIG_MODULES_USE_ELF_RELA as the '=y' part was optional and it did not test the rest of the line. When this happens, ktest will stop checking the rest of the configs but it will also think that no modules are needed to be installed. What it should do is only jump out of the loop if it actually found a CONFIG_MODULES that is set to true. Otherwise, ktest wont install the necessary modules needed for proper booting of the test target. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

This patch modifies the dts file of Samsung Trats board to define four sections of 256MiB instead of two of 512MiB to fix the boot problem.

To fix this introduce a s3c64xx_spi_setname function and populate all Samsung arches with the correct names. The function resides in a new header, as the s3c64xx-spi.h contains driver platform data and should therefore at some later point move out of the Samsung include dir. Tested on a s3c2416-based machine.

Without these clock aliases the dmtimer driver will fail to find the parent clocks for the dmtimer. Verified that DMTIMERs can be successfully requested on AM335x beagle bone.
