* ext4: make the zero-out chunk size tunableZheng Liu2012-08-174-12/+32
| | | | | | | | | | | | | | | | | Currently in ext4 the length of zero-out chunk is set to 7 file system blocks. But if an inode has uninitailized extents from using fallocate to preallocate space, and the workload issues many random writes, this can cause a fragmented extent tree that will unnecessarily grow the extent tree. So create a new sysfs tunable, extent_max_zeroout_kb, which controls the maximum size where blocks will be zeroed out instead of creating a new uninitialized extent. The default of this has been sent to 32kb.

* ext4: realign trace events structs to make it smallerAnatol Pomozov2012-08-171-120/+120
| | | | | | | | | | | | | | | | | Most hardware architectures require that data (including struct fields) have to be aligned in memory. To make it happen compiler inserts padding between struct fields if they are not aligned correctly. Reorder fields to remove paddings and make structures denser. Making data smaller saves some memory that is very important for trace events. Tracing buffer has limited size and making objects smaller we can put more of them without overflowing the tracing buffer. To find data struct holes I used 'pahole -H 1 -E -I vmlinux.o' from 'dwarves' package. Signed-off-by: Anatol Pomozov <anatol.pomozov@gmail.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
* ext4: add max_dir_size_kb mount optionTheodore Ts'o2012-08-174-0/+25
| | | | | | | | | | | | | | | | | | | | | | Very large directories can cause significant performance problems, or perhaps even invoke the OOM killer, if the process is running in a highly constrained memory environment (whether it is VM's with a small amount of memory or in a small memory cgroup). So it is useful, in cloud server/data center environments, to be able to set a filesystem-wide cap on the maximum size of a directory, to ensure that directories never get larger than a sane size. We do this via a new mount option, max_dir_size_kb. If there is an attempt to grow the directory larger than max_dir_size_kb, the system call will return ENOSPC instead.

* ext4: collapse a single extent tree block into the inode if possibleTheodore Ts'o2012-08-171-14/+58
| | | | | | | | | | | | | | | If an inode has more than 4 extents, but then later some of the extents are merged together, we can optimize the file system by moving the extents up into the inode, and discarding the extent tree block. This is important, because if there are a large number of inodes with an external extent tree blocks where the contents could fit in the inode, this can significantly increase the fsck time of the file system.

* ext4: don't call ext4_error while block group is lockedTheodore Ts'o2012-08-172-26/+37
| | | | | | | | | | | | | | | | | | | While in ext4_validate_block_bitmap(), if an block allocation bitmap is found to be invalid, we call ext4_error() while the block group is still locked. This causes ext4_commit_super() to call a function which might sleep while in an atomic context. There's no need to keep the block group locked at this point, so hoist the ext4_error() call up to ext4_validate_block_bitmap() and release the block group spinlock before calling ext4_error().

* ext4: make sure the journal sb is written in ext4_clear_journal_err()Theodore Ts'o2012-08-053-1/+4
| | | | | | | | | | | | | | | | | | | | After we transfer set the EXT4_ERROR_FS bit in the file system superblock, it's not enough to call jbd2_journal_clear_err() to clear the error indication from journal superblock --- we need to call jbd2_journal_update_sb_errno() as well. Otherwise, when the root file system is mounted read-only, the journal is replayed, and the error indicator is transferred to the superblock --- but the s_errno field in the jbd2 superblock is left set (since although we cleared it in memory, we never flushed it out to disk). This can end up confusing e2fsck. We should make e2fsck more robust in this case, but the kernel shouldn't be leaving things in this confused state, either.
