* sparc64: Directly call xcall_deliver() in smp_start_sync_tick_client.David S. Miller2008-08-04

* sparc64: Call xcall_deliver() directly in some cases.David S. Miller2008-08-04
| | | | | | | | | | | | | | | | | | | | For these cases the callers make sure: 1) The cpus indicated are online. 2) The current cpu is not in the list of indicated cpus. Therefore we can pass a pointer to the mask directly. One of the motivations in this transformation is to make use of "&cpumask_of_cpu(cpu)" which evaluates to a pointer to constant data in the kernel and thus takes up no stack space. Hopefully someone in the future will change the interface of arch_send_call_function_ipi() such that it passes a const cpumask_t pointer so that this will optimize ever further.

| * ext4: Fix lack of credits BUG() when deleting a badly fragmented inodeTheodore Ts'o2008-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The extents codepath for ext4_truncate() requests journal transaction credits in very small chunks, requesting only what is needed. This means there may not be enough credits left on the transaction handle after ext4_truncate() returns and then when ext4_delete_inode() tries finish up its work, it may not have enough transaction credits, causing a BUG() oops in the jbd2 core. Also, reserve an extra 2 blocks when starting an ext4_delete_inode() since we need to update the inode bitmap, as well as update the orphaned inode linked list.

| * ext4: Fix ext4_ext_journal_restart()Theodore Ts'o2008-08-01
| | | | | | | | | | | | | | | | | | | | | | | | | | The ext4_ext_journal_restart() is a convenience function which checks to see if the requested number of credits is present, and if so it closes the current transaction and attaches the current handle to the new transaction. Unfortunately, it wasn't proprely checking the return value from ext4_journal_extend(), so it was starting a new transaction when one was not necessary, and returning an error when all that was necessary was to restart the handle with a new transaction.

| * jbd2: don't abort if flushing file data failedHidehiro Kawai2008-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In ordered mode, the current jbd2 aborts the journal if a file data buffer has an error. But this behavior is unintended, and we found that it has been adopted accidentally. This patch undoes it and just calls printk() instead of aborting the journal. Unlike a similar patch for ext3/jbd, file data buffers are written via generic_writepages(). But we also need to set AS_EIO into their mappings because wait_on_page_writeback_range() clears AS_EIO before a user process sees it.

| * ext4: don't read inode block if the buffer has a write errorHidehiro Kawai2008-07-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A transient I/O error can corrupt inode data. Here is the scenario: (1) update inode_A at the block_B (2) pdflush writes out new inode_A to the filesystem, but it results in write I/O error, at this point, BH_Uptodate flag of the buffer for block_B is cleared and BH_Write_EIO is set (3) create new inode_C which located at block_B, and __ext4_get_inode_loc() tries to read on-disk block_B because the buffer is not uptodate (4) if it can read on-disk block_B successfully, inode_A is overwritten by old data This patch makes __ext4_get_inode_loc() not read the inode block if the buffer has BH_Write_EIO flag. In this case, the buffer should have the latest information, so setting the uptodate flag to the buffer (this avoids WARN_ON_ONCE() in mark_buffer_dirty().) According to this change, we would need to test BH_Write_EIO flag for the error checking. Currently nobody checks write I/O errors on metadata buffers, but it will be done in other patches I'm working on.

| * ext4: Don't allow lg prealloc list to be grow large.Aneesh Kumar K.V2008-07-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the locality group prealloc list is freed only when there is a block allocation failure. This can result in large number of entries in the preallocation list making ext4_mb_use_preallocated() expensive. To fix this, we convert the locality group prealloc list to a hash list. The hash index is the order of number of blocks in the prealloc space with a max order of 9. When adding prealloc space to the list we make sure total entries for each order does not exceed 8. If it is more than 8 we discard few entries and make sure the we have only <= 5 entries. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>

| * ext4: lock block groups when initializingEric Sandeen2008-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed when filling a 1T filesystem with 4 threads using the fs_mark benchmark: fs_mark -d /mnt/test -D 256 -n 100000 -t 4 -s 20480 -F -S 0 that I occasionally got checksum mismatch errors: EXT4-fs error (device sdb): ext4_init_inode_bitmap: Checksum bad for group 6935 etc. I'd reliably get 4-5 of them during the run. It appears that the problem is likely a race to init the bg's when the uninit_bg feature is enabled. With the patch below, which adds sb_bgl_locking around initialization, I was able to complete several runs with no errors or warnings.

| * ext4: sync up block and inode bitmap reading functionsEric Sandeen2008-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ext4_read_block_bitmap and read_inode_bitmap do essentially the same thing, and yet they are structured quite differently. I came across this difference while looking at doing bg locking during bg initialization. This patch: * removes unnecessary casts in the error messages * renames read_inode_bitmap to ext4_read_inode_bitmap * and more substantially, restructures the inode bitmap reading function to be more like the block bitmap counterpart. The change to the inode bitmap reader simplifies the locking to be applied in the next patch. Signed-off-by: Eric Sandeen <sandeen@redhat.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>

| * ext4: Fix data corruption when writing to prealloc areaAneesh Kumar K.V2008-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Inserting an extent can cause a new entry in the already existing index block. That doesn't increase the depth of the instead. Instead it adds a new leaf block. Now with the new leaf block the path information corresponding to the logical block should be fetched from the new block. The old path will be pointing to the old leaf block. We need to recalucate the path information on extent insert even if depth doesn't change. Without this change, the extent merge after converting an unwritten extent to initialized extent takes the wrong extent and cause data corruption.

| * | [ARM] pxa: add support for L2 outer cache on XScale3 (attempt 2)Eric Miao2008-07-28

No idea what happened. This puts back the missing bits. --rmk) The initial patch from Lothar, and Lennert make it into a cleaner one, modified and tested on PXA320 by Eric Miao. This patch moves the L2 cache operations out of proc-xsc3.S into dedicated outer cache support code. CACHE_XSC3L2 can be deselected so no L2 cache specific code will be linked in, and that L2 enable bit will not be set, this applies to the following cases: a. _only_ PXA300/PXA310 support included and no L2 cache wanted b. PXA320 support included, but want L2 be disabled So the enabling of L2 depends on two things: - CACHE_XSC3L2 is selected - and L2 cache is present Where the latter is only a safeguard (previous testing shows it works OK even when this bit is turned on). IXP series of processors with XScale3 cannot disable L2 cache for the moment since they depend on the L2 cache for its coherent memory, so IXP may always select CACHE_XSC3L2. Other L2 relevant bits are always turned on (i.e. the original code enclosed by #if L2_CACHE_ENABLED .. #endif), as they showed no side effects.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The story is that what we used to do when we actually used smp_report_regs() is that if you specifically only wanted to have the current cpu's registers dumped you would call "__show_regs()" otherwise you would call show_regs() which also invoked smp_report_regs(). Now that we killed off smp_report_regs() there is no longer any reason to have these two routines, just show_regs() is sufficient. Also kill off a stray declaration of show_regs() in sparc64_ksym.c Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some of them use 'bool' and whatnot and therefore are not kosher for userspace, so don't export them there. Reported by Roland McGrath. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All the call sites are #if 0'd out and we have a much more useful global cpu dumping facility these days. smp_report_regs() is way too verbose to be usable. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It just clutters everything up and even though I wrote that hack I can't remember having used it in the last 5 years or so. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We already have code that does this, but it is only currently attached to sysrq-'y'. Signed-off-by: David S. Miller <davem@davemloft.net>
