Subject: workqueue: Fix flag collision
From: Ben Hutchings <ben@xxxxxxxxxxxxxxx>
commit fbf1c41fc0f4d3574ac2377245efd666c1fa3075 upstream.
Commit 0a94efb5acbb ("workqueue: implicit ordered attribute should be
overridable") introduced a __WQ_ORDERED_EXPLICIT flag but gave it the
same value as __WQ_LEGACY. I don't believe these were intended to
mean the same thing, so renumber __WQ_ORDERED_EXPLICIT.
Fixes: 0a94efb5acbb ("workqueue: implicit ordered attribute should be ...")
