Btrfs: Reorder tests in set_extent_bit to properly find holes
...
Yan Zheng noticed that set_extent_bit was exiting too early when there
was a hole in the map. The fix is to reorder the tests to check for the
hole first.

Btrfs: Add more synchronization before creating a snapshot
...
File data checksums are only done during writepage, so we have to make sure
all pages are written when the snapshot is taken. This also adds some
locking so that new writes don't race in and add new dirty pages.

Btrfs: Add run time btree defrag, and an ioctl to force btree defrag
...
This adds two types of btree defrag, a run time form that tries to
defrag recently allocated blocks in the btree when they are still in ram,
and an ioctl that forces defrag of all btree blocks.
File data blocks are not defragged yet, but this can make a huge difference
in sequential btree reads.
