[PATCH 00/11] btrfs: fixes around swap file activation and cleanups

[fdmanana@kernel.org]

From: Filipe Manana <fdmanana@suse.com>

There are a couple issues with swap file activation, one being races with
memory mapped writes, while the other one is a failure due to buggy
detection of extent sharedness - we can often consider an extent as shared
when it is not but it used to be. The rest are just some cleanups or
enhancements.

Filipe Manana (11):
  btrfs: fix race with memory mapped writes when activating swap file
  btrfs: fix swap file activation failure due to extents that used to be shared
  btrfs: allow swap activation to be interruptible
  btrfs: avoid monopolizing a core when activating a swap file
  btrfs: remove no longer needed strict argument from can_nocow_extent()
  btrfs: remove the snapshot check from check_committed_ref()
  btrfs: avoid redundant call to get inline ref type at check_committed_ref()
  btrfs: simplify return logic at check_committed_ref()
  btrfs: simplify arguments for btrfs_cross_ref_exist()
  btrfs: add function comment for check_committed_ref()
  btrfs: add assertions and comment about path expectations to btrfs_cross_ref_exist()
