Linus Torvalds c1a198d923 Merge branch 'for-linus-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs ... Pull btrfs updates from Chris Mason: "This has our usual assortment of fixes and cleanups, but the biggest change included is Omar Sandoval's free space tree. It's not the default yet, mounting -o space_cache=v2 enables it and sets a readonly compat bit. The tree can actually be deleted and regenerated if there are any problems, but it has held up really well in testing so far. For very large filesystems (30T+) our existing free space caching code can end up taking a huge amount of time during commits. The new tree based code is faster and less work overall to update as the commit progresses. Omar worked on this during the summer and we'll hammer on it in production here at FB over the next few months" * 'for-linus-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: (73 commits) Btrfs: fix fitrim discarding device area reserved for boot loader's use Btrfs: Check metadata redundancy on balance btrfs: statfs: report zero available if metadata are exhausted btrfs: preallocate path for snapshot creation at ioctl time btrfs: allocate root item at snapshot ioctl time btrfs: do an allocation earlier during snapshot creation btrfs: use smaller type for btrfs_path locks btrfs: use smaller type for btrfs_path lowest_level btrfs: use smaller type for btrfs_path reada btrfs: cleanup, use enum values for btrfs_path reada btrfs: constify static arrays btrfs: constify remaining structs with function pointers btrfs tests: replace whole ops structure for free space tests btrfs: use list_for_each_entry* in backref.c btrfs: use list_for_each_entry_safe in free-space-cache.c btrfs: use list_for_each_entry* in check-integrity.c Btrfs: use linux/sizes.h to represent constants btrfs: cleanup, remove stray return statements btrfs: zero out delayed node upon allocation btrfs: pass proper enum type to start_transaction() ...		2016-01-18 12:44:40 -08:00
