Btrfs: [PATCH] extent_map: make the writepage_io hook optional 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: Christoph Hellwig <hch@lst.de> Signed-off-by: Chris Mason <chris.mason@oracle.com>
