[PATCH 0/7] btrfs: a fix for fsync and a few improvements to the full fsync path

[fdmanana@kernel.org]

From: Filipe Manana <fdmanana@suse.com>

This fixes a bug (first patch) with preallocated extents beyond eof being
lost after a full fsync and a power failure. The rest is mostly some
improvements to the full fsync code path (less IO, use less memory for
logging checksums, etc), and silence smatch about a possible dereference
of an uninitialized pointer. More details in the changelogs.

Filipe Manana (7):
  btrfs: fix lost prealloc extents beyond eof after full fsync
  btrfs: stop copying old file extents when doing a full fsync
  btrfs: hold on to less memory when logging checksums during full fsync
  btrfs: voluntarily relinquish cpu when doing a full fsync
  btrfs: reset last_reflink_trans after fsyncing inode
  btrfs: fix unexpected error path when reflinking an inline extent
  btrfs: deal with unexpected extent type during reflinking
