* Btrfs: [PATCH] extent_map: add writepage_end_io hookChristoph Hellwig2007-09-101-0/+1
| | | | | | | | | | | | | 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: Christoph Hellwig <hch@lst.de> Signed-off-by: Chris Mason <chris.mason@oracle.com>
* Btrfs: [PATCH] extent_map: provide generic bmapChristoph Hellwig2007-09-101-0/+2
| | | | | | | | | | 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.
