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.

Btrfs: [PATCH] extent_map: provide generic bmap
...
generic_bmap is completely trivial, while the extent to bh mapping in
btrfs is rather complex. So provide a extent_bmap instead that takes
a get_extent callback and can be used by filesystem using the extent_map
code.
