-Date: Sat Feb 1 21:40:51 2014 -0700

- Remove reference to <linux/btrfs.h>, and instead use <btrfs/ioctl.h> like we're supposed to (from btrfs-progs)
-
- This fixes compilation issues when btrfs.h isn't available (because we just need the relevant structs, which for userspace programs are supposed to come from btrfs-progs instead of the kernel headers).

-Subject: [PATCH 2/4] Avoid buffering to tempfile when pushing with V2
-
-The practice of buffering to a tempfile during a pushing contributes massively
-to slow V2 push performance perception. The protocol was actually designed to
-avoid precalculation, supporting cut-through data push. This means we can
-assemble the layer, calculate its digest and push to the remote endpoint, all
-at the same time.
-
-This should increase performance massively on systems with slow disks or IO
-bottlenecks.
