  configfs: Introduce config_item_get_unless_zero() (2017-06-12 13:20:20 +0200)

----------------------------------------------------------------
A fix from Nic for a race seen in production (including a stable tag).
And while I'm sending you this I'm also sneaking in a trivial new helper
from Bart so that we don't need inter-tree dependencies for the next merge
window.
