[PATCH 0/2] btrfs: some optimizations for send

[fdmanana@kernel.org]

From: Filipe Manana <fdmanana@suse.com>

The following are two optimizations for send, one to avoid sending
unnecessary holes (writes full of zeros), which can waste a lot of space
at the receiver and increase stream size for cases where sparse files are
used, such as images of thin provisioned filesystems for example as
recently reported by a user. The second is just a small optimization to
avoid repeating a btree search. More details in the respective change logs.

Filipe Manana (2):
  btrfs: send: don't issue unnecessary zero writes for trailing hole
  btrfs: send: avoid duplicated search for last extent when sending hole
