[GIT PULL] Btrfs fixes

[Chris Mason <clm@fb.com>]

Hi Linus,

Dave Sterba queued up a few fixes for btrfs.  I have them in my
for-linus-4.10 branch:

These are all over the place.  The tracepoint part of the pull fixes a
crash and adds a little more information to two tracepoints, while the
rest are good old fashioned fixes.
