Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull btrfs fixes from Chris Mason: "These are mostly bug fixes and a two small performance fixes. The most important of the bunch are Josef's fix for a snapshotting regression and Mark's update to fix compile problems on arm" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: (25 commits) Btrfs: create the uuid tree on remount rw btrfs: change extent-same to copy entire argument struct Btrfs: dir_inode_operations should use btrfs_update_time also btrfs: Add btrfs: prefix to kernel log output btrfs: refuse to remount read-write after abort Btrfs: btrfs_ioctl_default_subvol: Revert back to toplevel subvolume when arg is 0 Btrfs: don't leak transaction in btrfs_sync_file() Btrfs: add the missing mutex unlock in write_all_supers() Btrfs: iput inode on allocation failure Btrfs: remove space_info->reservation_progress Btrfs: kill delay_iput arg to the wait_ordered functions Btrfs: fix worst case calculator for space usage Revert "Btrfs: rework the overcommit logic to be based on the total size" Btrfs: improve replacing nocow extents Btrfs: drop dir i_size when adding new names on replay Btrfs: replay dir_index items before other items Btrfs: check roots last log commit when checking if an inode has been logged Btrfs: actually log directory we are fsync()'ing Btrfs: actually limit the size of delalloc range Btrfs: allocate the free space by the existed max extent size when ENOSPC ...
