Merge branch 'for-linus-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull btrfs fixes from Chris Mason:
"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"
* 'for-linus-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs:
btrfs: make tracepoint format strings more compact
Btrfs: add truncated_len for ordered extent tracepoints
Btrfs: add 'inode' for extent map tracepoint
btrfs: fix crash when tracepoint arguments are freed by wq callbacks
Btrfs: adjust outstanding_extents counter properly when dio write is split
Btrfs: fix lockdep warning about log_mutex
Btrfs: use down_read_nested to make lockdep silent
btrfs: fix locking when we put back a delayed ref that's too new
btrfs: fix error handling when run_delayed_extent_op fails
btrfs: return the actual error value from from btrfs_uuid_tree_iterate
