Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: (114 commits) Btrfs: check for a null fs root when writing to the backup root log Btrfs: fix race during transaction joins Btrfs: fix a potential btrfs_bio leak on scrub fixups Btrfs: rename btrfs_bio multi -> bbio for consistency Btrfs: stop leaking btrfs_bios on readahead Btrfs: stop the readahead threads on failed mount Btrfs: fix extent_buffer leak in the metadata IO error handling Btrfs: fix the new inspection ioctls for 32 bit compat Btrfs: fix delayed insertion reservation Btrfs: ClearPageError during writepage and clean_tree_block Btrfs: be smarter about committing the transaction in reserve_metadata_bytes Btrfs: make a delayed_block_rsv for the delayed item insertion Btrfs: add a log of past tree roots btrfs: separate superblock items out of fs_info Btrfs: use the global reserve when truncating the free space cache inode Btrfs: release metadata from global reserve if we have to fallback for unlink Btrfs: make sure to flush queued bios if write_cache_pages waits Btrfs: fix extent pinning bugs in the tree log Btrfs: make sure btrfs_remove_free_space doesn't leak EAGAIN Btrfs: don't wait as long for more batches during SSD log commit ...
