We need device delete from the dev_list so create a new function. New instead of refactor of btrfs_free_stale_device() because, btrfs_free_stale_device() doesn't hold device_list_mutex which is actually needed here. Signed-off-by: Anand Jain <anand.jain@oracle.com> --- v1: title of this patch btrfs: refactor btrfs_free_stale_device() to get device list delete v2: delete_device_from_list() is not pealed from btrfs_free_stale_device() as this needs device_list_mutex. And its static now. v3: Send to correct ML v4: no change v5: use helper free_device() fs/btrfs/volumes.c | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+)
