[PATCH 00/11] Device fixes and cleanups

[David Sterba <dsterba@suse.com>]

Cleanups for device locking and documentation of the various mutexes.
Patch 1 is a bugfix that could be considered for 4.15 as we could leak bios
under some rare condition, but so far this hasn't been reported so I don't rate
is as critical.

David Sterba (11):
  btrfs: add missing device::flush_bio puts
  btrfs: rename device free rcu helper to free_device_rcu
  btrfs: introduce free_device helper
  btrfs: use free_device where opencoded
  btrfs: simplify exit paths in btrfs_init_new_device
  btrfs: document device locking
  btrfs: dev_alloc_list is not protected by RCU, use normal list_del
  btrfs: simplify btrfs_close_bdev
  btrfs: switch to RCU for device traversal in btrfs_ioctl_dev_info
  btrfs: switch to RCU for device traversal in btrfs_ioctl_fs_info
  btrfs: use non-RCU list traversal in write_all_supers callees
