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

a get_extent callback and can be used by filesystem using the extent_map
code.

Btrfs: [PATCH] extent_map: fix locking for bio completion

The bio completion handlers can be run in any context, e.g. when using
the old ide driver they run in hardirq context with irqs disabled so
lockdep rightfully warns about using write_lock_irq useage in these
handlers.

This patch switches clear_extent_bit and set_extent_bit to
write_lock_irqsave to fix this problem.
