[GIT PULL] Btrfs updates for 6.1-rc7

[David Sterba]

Hi,

a few more fixes from past two weeks. Please pull, thanks.

- fix a regression in nowait + buffered write

- in zoned mode fix endianness when comparing super block generation

- locking and lockdep fixes:
  - fix potential sleeping under spinlock when setting qgroup limit
  - lockdep warning fixes when btrfs_path is freed after copy_to_user
  - do not modify log tree while holding a leaf from fs tree locked

- fix freeing of sysfs files of static features on error

- use kv.alloc for zone map allocation as a fallback to avoid warnings
  due to high order allocation

- send, avoid unaligned encoded writes when attempting to clone range
