[PULL] Btrfs tracepoint updates for 4.10

[David Sterba <dsterba@suse.com>]

Hi,

I've selected a handful of tracepoint fixes and updates. The fixes a crash when
tracepoints are enabled so this can be considered urgent, the others are minor
harmless improvements. The qgroup tracepoint update is not included as it
depends on other patches so it'll possibly go later or with the rest of the
qgroup patches.

The following changes since commit 2939e1a86f758b55cdba73e29397dd3d94df13bc:

  btrfs: limit async_work allocation and worker func duration (2016-12-13 11:01:30 -0800)
