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
