[PATCH v4 0/6] preparatory work to add device forget

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

v3->v4:
 Mainly fix as per comments from Josef.
 @3/6: rename btrfs_free_stale_device() to btrfs_free_stale_devices()
 @4/6: reorg logic, init not_found = 0; drop else part
 @5/6: added new in v4. Renames arg cur_dev to skip_dev
 @6/6: v3:5/6 is merged to v4:6/6
 checkpath error fixes.

v2->v3:
 @ 6/6:
 add btrfs_free_stale_device() fn description, suggested by Nikolay
 Fix line with longer than 80 char
 
v1->v2:
 @ 6/6:
 btrfs_device::name is null when we have missing device and
 unmounted. So we still need to check for dev->name.

We can reuse the function btrfs_free_stale_device() to add feature
to forget a scanned device or all stale devices. So this patch set
proposes following changes to it.

Anand Jain (6):
  btrfs: cleanup btrfs_free_stale_device() usage
  btrfs: no need to check for btrfs_fs_devices::seeding
  btrfs: make btrfs_free_stale_device() to iterate all stales
  btrfs: make btrfs_free_stale_device() argument optional
  btrfs: rename btrfs_free_stale_devices() arg to skip_dev
  btrfs: make btrfs_free_stale_device() to match the path
