2010-05-16ext4: init statistics after journal recoveryDmitry Monakhov
Currently block/inode/dir counters initialized before journal was recovered. In fact after journal recovery this info will probably change. And freeblocks it critical for correct delalloc mode accounting. https://bugzilla.kernel.org/show_bug.cgi?id=15768 Signed-off-by: Dmitry Monakhov <dmonakhov@openvz.org> Acked-by: Jan Kara <jack@suse.cz> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2010-05-16ext4: clean up inode bitmaps manipulation in ext4_free_inodeDmitry Monakhov
- Reorganize locking scheme to batch two atomic operation in to one. This also allow us to state what healthy group must obey following rule ext4_free_inodes_count(sb, gdp) == ext4_count_free(inode_bitmap, NUM); - Fix possible undefined pointer dereference. - Even if group descriptor stats aren't accessible we have to update inode bitmaps. - Move non-group members update out of group_lock.

2010-05-16ext4: Do not zero out uninitialized extents beyond i_sizeDmitry Monakhov
The extents code will sometimes zero out blocks and mark them as initialized instead of splitting an extent into several smaller ones. This optimization however, causes problems if the extent is beyond i_size because fsck will complain if there are uninitialized blocks after i_size as this can not be distinguished from an inode that has an incorrect i_size field. https://bugzilla.kernel.org/show_bug.cgi?id=15742 Signed-off-by: Dmitry Monakhov <dmonakhov@openvz.org> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2010-05-16jbd2: Improve scalability by not taking j_state_lock in jbd2_journal_stop()Theodore Ts'o
One of the most contended locks in the jbd2 layer is j_state_lock when running dbench. This is especially true if using the real-time kernel with its "sleeping spinlocks" patch that replaces spinlocks with priority inheriting mutexes --- but it also shows up on large SMP benchmarks. Thanks to John Stultz for pointing this out. Reviewed by Mingming Cao and Jan Kara. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2010-05-16ext4: don't scan/accumulate more pages than mballoc will allocateEric Sandeen
There was a bug reported on RHEL5 that a 10G dd on a 12G box had a very, very slow sync after that. At issue was the loop in write_cache_pages scanning all the way to the end of the 10G file, even though the subsequent call to mpage_da_submit_io would only actually write a smallish amt; then we went back to the write_cache_pages loop ... wasting tons of time in calling __mpage_da_writepage for thousands of pages we would just revisit (many times) later. Upstream it's not such a big issue for sys_sync because we get to the loop with a much smaller nr_to_write, which limits the loop. However, talking with Aneesh he realized that fsync upstream still gets here with a very large nr_to_write and we face the same problem. This patch makes mpage_add_bh_to_extent stop the loop after we've accumulated 2048 pages, by setting mpd->io_done = 1; which ultimately causes the write_cache_pages loop to break. Repeating the test with a dirty_ratio of 80 (to leave something for fsync to do), I don't see huge IO performance gains, but the reduction in cpu usage is striking: 80% usage with stock, and 2% with the below patch. Instrumenting the loop in write_cache_pages clearly shows that we are wasting time here. Eventually we need to change mpage_da_map_pages() also submit its I/O to the block layer, subsuming mpage_da_submit_io(), and then change it call ext4_get_blocks() multiple times.

2010-05-16ext4: stop issuing discards if not supported by deviceEric Sandeen
Turn off issuance of discard requests if the device does not support it - similar to the action we take for barriers. This will save a little computation time if a non-discardable device is mounted with -o discard, and also makes it obvious that it's not doing what was asked at mount time ...

2010-05-09cpuidle: Fix incorrect optimizationArjan van de Ven
commit 672917dcc78 ("cpuidle: menu governor: reduce latency on exit") added an optimization, where the analysis on the past idle period moved from the end of idle, to the beginning of the new idle. Unfortunately, this optimization had a bug where it zeroed one key variable for new use, that is needed for the analysis. The fix is simple, zero the variable after doing the work from the previous idle. During the audit of the code that found this issue, another issue was also found; the ->measured_us data structure member is never set, a local variable is always used instead.

2010-05-07md: restore ability of spare drives to spin down.NeilBrown
Some time ago we stopped the clean/active metadata updates from being written to a 'spare' device in most cases so that it could spin down and say spun down. Device failure/removal etc are still recorded on spares. However commit 51d5668cb2e3fd1827a55 broke this 50% of the time, depending on whether the event count is even or odd. The change log entry said: This means that the alignment between 'odd/even' and 'clean/dirty' might take a little longer to attain, how ever the code makes no attempt to create that alignment, so it could take arbitrarily long. So when we find that clean/dirty is not aligned with odd/even, force a second metadata-update immediately. There are already cases where a second metadata-update is needed immediately (e.g. when a device fails during the metadata update). We just piggy-back on that.

An earlier regression fix for the mxb driver (V4L/DVB: saa7146_vv: fix regression where v4l2_device was registered too late) caused a new regression in the av7110 driver. Reverted the old fix and fixed the problem in the mxb driver instead. Tested on mxb and budget-av cards. The real problem is that the saa7146 framework has separate probe() and attach() driver callbacks which should be rolled into one. This is now done for the mxb driver, but others should do the same. Lack of hardware makes this hard to do, though. I hope to get hold of some hexium cards and then I can try to improve the framework to prevent this from happening again.
