[PATCH 0/2] send: Avoid sending disknr==0 and PREALLOC extents when possible V3
These two patches address the issue of sending unneeded zero data for
disknr==0 and PREALLOC extents.
There is room for additional improvement for PREALLOC extents, but it
requires adding a new send command, so for now this is not addressed.
Changes in V2: no functional change; previous patchset was malformed,
so cleanup done with checkpatch.pl.
Changes in V3: rebased against btrfs-next
Alex Lyakas (2):
Avoid sending disknr==0 extents when possible.
On a diff-send, avoid sending PREALLOC extents, if the parent
root has only PREALLOC extents on an appropriate file range.

Hi Josef, is there still an issue with applying the patch? Thanks, Alex.
