Btrfs: Find and remove dead roots the first time a root is loaded.
...
Dead roots are trees left over after a crash, and they were either in the
process of being removed or were waiting to be removed when the box crashed.
Before, a search of the entire tree of root pointers was done on mount
looking for dead roots. Now, the search is done the first time we load
a root.
This makes mount faster when there are a large number of snapshots, and it
enables the block accounting code to properly update the block counts on
the latest root as old versions of the root are reaped after a crash.

Btrfs: [PATCH] extent_map: add writepage_end_io hook
...
XFS updates the ondisk inode size only after the data I/O has finished,
so it needs a hook when the writepage end_bio handler has finished.
Might not be worth applying as-is as the per-page callback is very
ineffcient. What XFS really wants is a callback when writeout of a
whole extent has completed. This delayed i_size updates scheme might
be worthwile for btrfs aswell, btw.
