Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull btrfs update frm Chris Mason: "This is our usual merge window set of bug fixes, performance improvements and cleanups. Miao Xie has some really nice optimizations for writeback. Josef also expanded our sanity checks quite a bit; these make up a big chunk of the new lines" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: (98 commits) Btrfs: rename btrfs_start_all_delalloc_inodes Btrfs: don't wait for the completion of all the ordered extents Btrfs: don't wait for all the async delalloc when shrinking delalloc Btrfs: fix the confusion between delalloc bytes and metadata bytes Btrfs: pick up the code for the item number calculation in flush_space() Btrfs: wait for the ordered extent only when we want Btrfs: remove unnecessary initialization and memory barrior in shrink_delalloc() Btrfs: avoid unnecessary scrub workers allocation Btrfs: check file extent type before anything else btrfs: Remove useless variable in write_ctree_super() btrfs: Fix checkpatch.pl warning of spacing issues btrfs: Replace kmalloc with kmalloc_array btrfs: Enclose macros with complex values within parenthesis btrfs: Use WARN_ON()'s return value in place of WARN_ON(1) btrfs: Remove redundant local zero structure btrfs: Pack struct btrfs_device btrfs: Replace multiple atomic_inc() with atomic_add() btrfs: Add helper function for free_root_pointers() Btrfs: fix a crash when running balance and defrag concurrently Btrfs: do not run snapshot-aware defragment on error ...
