[PATCH 0/6] fix device_list_mutex usage and cleanups in device_list_add()

[Anand Jain <anand.jain@oracle.com>]

Patch 1/6 is a preparatory patch to add the required device_list_mutex
in device_list_add() in the patch 2/6.

Patch 3/6 updates the comments on device_list_mutex.

Patch 4/6 is just a cleanup patch no functional changes.

Patch 5/6 adds the required device_list_mutex in
btrfs_free_stale_device().

Patch 6/6 renames btrfs_free_stale_device() to free_stale_device(), no
functional changes.

Anand Jain (6):

  btrfs: fix device_list_add() missing device_list_mutex()
  btrfs: update device_list_mutex protected items

  btrfs: fix btrfs_free_stale_devices() with needed locks
