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. Signed-off-by: NChristoph Hellwig <hch@lst.de> Signed-off-by: NChris Mason <chris.mason@oracle.com>

The writepage_io is not mandatory, e.g. my port of xfs to the extent_map code does not have one for now. So handle a NULL pointer gracefully here. Signed-off-by: NChristoph Hellwig <hch@lst.de> Signed-off-by: NChris Mason <chris.mason@oracle.com>

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.

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. Signed-off-by: NChristoph Hellwig <hch@lst.de> Signed-off-by: NChris Mason <chris.mason@oracle.com>

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. Signed-off-by: NChris Mason <chris.mason@oracle.com>
