Revision adaa4b8e4d47eeb114513c2f7a172929154b94bd authored by Jan Schmidt on 21 March 2013, 14:30:23 UTC, committed by Josef Bacik on 28 March 2013, 13:51:26 UTC 
Btrfs: fix EIO from btrfs send in is_extent_unchanged for punched holes
 
When you take a snapshot, punch a hole where there has been data, then take
another snapshot and try to send an incremental stream, btrfs send would
give you EIO. That is because is_extent_unchanged had no support for holes
being punched. With this patch, instead of returning EIO we just return
0 (== the extent is not unchanged) and we're good.
