2008-04-29ext4: Fix hang on umount with quotas when journal is abortedJan Kara
Call dquot_drop() from ext4_dquot_drop() even if we fail to start a transaction. Otherwise we never get to dropping references to quota structures from the inode and umount will hang indefinitely.

2008-04-29jbd2: only create debugfs and stats entries if init is successfulDuane Griffin

2008-04-17jbd2: replace potentially false assertion with if blockDuane Griffin
If an error occurs during jbd2 cache initialisation it is possible for the journal_head_cache to be NULL when jbd2_journal_destroy_journal_head_cache is called. Replace the J_ASSERT with an if block to handle the situation correctly. Note that even with this fix things will break badly if jbd2 is statically compiled in and cache initialisation fails.

This is needed so that delayed allocation doesn't do block reservation for prealloc space since the blocks are already reserved on disk. Mark the buffer head unwritten.

2008-04-29ext4: Fix race between migration and mmap writeAneesh Kumar K.V
Fail migrate if we allocated new blocks via mmap write. If we write to holes in the file via mmap, we end up allocating new blocks. This block allocation happens without taking inode->i_mutex. Since migrate is protected by i_mutex and migrate expects that no new blocks get allocated during migrate, fail migrate if new blocks get allocated. We can't take inode->i_mutex in the mmap write path because that would result in a locking order violation between i_mutex and mmap_sem. Also adding a separate rw_sempahore for protection is really high overhead for a rare operation such as migrate.

This patch handles possible ENOSPC errors when writing to an uninitialized extent in case the filesystem is full. A write to a prealloc area causes the split of an unititalized extent into initialized and uninitialized extents. If we don't have space to add new extent information, instead of returning error, convert the existing uninitialized extent to initialized one. We need to zero out the blocks corresponding to the entire extent to prevent uninitialized data reaching userspace.

2008-04-17ext4: fdatasync should skip metadata writeout when overwritingHisashi Hifumi
Currently fdatasync is identical to fsync in ext3. I think fdatasync should skip journal flush in data=ordered and data=writeback mode when it overwrites to already-instantiated blocks on HDD. When I_DIRTY_DATASYNC flag is not set, fdatasync should skip journal writeout because this indicates only atime or/and mtime updates. Following patch is the same approach of ext2's fsync code(ext2_sync_file). I did a performance test using the sysbench. #sysbench --num-threads=128 --max-requests=50000 --test=fileio --file-total-size=128G --file-test-mode=rndwr --file-fsync-mode=fdatasync run The result on ext3 was: -2.6.24 Operations performed: 0 Read, 50080 Write, 59600 Other = 109680 Total Read 0b Written 782.5Mb Total transferred 782.5Mb (12.116Mb/sec) 775.45 Requests/sec executed Test execution summary: total time: 64.5814s total number of events: 50080 total time taken by event execution: 3713.9836 per-request statistics: min: 0.0000s avg: 0.0742s max: 0.9375s approx. 95 percentile: 0.2901s Threads fairness: events (avg/stddev): 391.2500/23.26 execution time (avg/stddev): 29.0155/1.99 -2.6.24-patched Operations performed: 0 Read, 50009 Write, 61596 Other = 111605 Total Read 0b Written 781.39Mb Total transferred 781.39Mb (16.419Mb/sec) 1050.83 Requests/sec executed Test execution summary: total time: 47.5900s total number of events: 50009 total time taken by event execution: 2934.5768 per-request statistics: min: 0.0000s avg: 0.0587s max: 0.8938s approx. 95 percentile: 0.1993s Threads fairness: events (avg/stddev): 390.6953/22.64 execution time (avg/stddev): 22.9264/1.17 Filesystem I/O throughput was improved.

2008-04-17jbd2: fix possible journal overflow issuesJosef Bacik
There are several cases where the running transaction can get buffers added to its BJ_Metadata list which it never dirtied, which makes its t_nr_buffers counter end up larger than its t_outstanding_credits counter. This will cause issues when starting new transactions as while we are logging buffers we decrement t_outstanding_buffers, so when t_outstanding_buffers goes negative, we will report that we need less space in the journal than we actually need, so transactions will be started even though there may not be enough room for them. In the worst case scenario (which admittedly is almost impossible to reproduce) this will result in the journal running out of space. The fix is to only refile buffers from the committing transaction to the running transactions BJ_Modified list when b_modified is set on that journal, which is the only way to be sure if the running transaction has modified that buffer. This patch also fixes an accounting error in journal_forget, it is possible that we can call journal_forget on a buffer without having modified it, only gotten write access to it, so instead of freeing a credit, we only do so if the buffer was modified. The assert will help catch if this problem occurs. Without these two patches I could hit this assert within minutes of running postmark, with them this issue no longer arises.

2008-04-17jbd2: fix the way the b_modified flag is clearedJosef Bacik
Currently at the start of a journal commit we loop through all of the buffers on the committing transaction and clear the b_modified flag (the flag that is set when a transaction modifies the buffer) under the j_list_lock. The problem is that everywhere else this flag is modified only under the jbd2 lock buffer flag, so it will race with a running transaction who could potentially set it, and have it unset by the committing transaction. This is also a big waste, you can have several thousands of buffers that you are clearing the modified flag on when you may not need to. This patch removes this code and instead clears the b_modified flag upon entering do_get_write_access/journal_get_create_access, so if that transaction does indeed use the buffer then it will be accounted for properly, and if it does not then we know we didn't use it. That will be important for the next patch in this series. Tested thoroughly by myself using postmark/iozone/bonnie++.

2008-04-29[IA64] Provide ACPI fixup for /proc/cpuinfo/physical_idAlex Chiang
Legacy HP ia64 platforms currently cannot provide /proc/cpuinfo/physical_id due to legacy SAL/PAL implementations. However, that physical topology information can be obtained via ACPI. Provide an interface that gives ACPI one last chance to provide physical_id for these legacy platforms. This logic only comes into play iff: - ACPI actually provides slot information for the CPU - we lack a valid socket_id Otherwise, we don't do anything. Since x86 uses the ACPI processor driver as well, we provide a nop stub function for arch_fix_phys_package_id() in asm-x86/topology.h Signed-off-by: Alex Chiang <achiang@hp.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
