Merge tag 'v3.12-rc2' into patchwork
Linux 3.12-rc2 * tag 'v3.12-rc2': (10774 commits) Linux 3.12-rc2 cfq: explicitly use 64bit divide operation for 64bit arguments block: Add nr_bios to block_rq_remap tracepoint 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 ...
