Hi everyone,

This first pull is the bulk of our changes for the next rc.  It is
against the 3.5 kernel so people testing the new features have a stable
point to work against.  This was tested against Linus' current tree as
well.

The second pull is just one fix against 3.6-rc1 (in another email).

Linus, please grab my for-linus branch:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus

Most of these fixes are against the new send/receive code.  Alexander
fixed a number of bugs in there and I found a more while backing up my
laptop.  It does nightly incremental runs now about 3x faster than
rsync, so things are looking pretty good.

On top of that we have fixes for some long standing bugs in the delayed
reference code (a few more of these are still being worked on),
deadlocks and other small fixes.
