ext4: fix free clusters calculation in bigalloc filesystem (2013-02-22 15:27:52 -0500)
----------------------------------------------------------------
The one new feature added in this patch series is the ability to use
the "punch hole" functionality for inodes that are not using extent
maps.
In the bug fix category, we fixed some races in the AIO and fstrim
code, and some potential NULL pointer dereferences and memory leaks in
error handling code paths.
In the optimization category, we fixed a performance regression in the
jbd2 layer introduced by commit d9b0193 (introduced in v3.0) which
shows up in the AIM7 benchmark. We also further optimized jbd2 by
minimize the amount of time that transaction handles are held active.
This patch series also features some additional enhancement of the
extent status tree, which is now used to cache extent information in a
more efficient/compact form than what we use on-disk.
