So, that's an issue in the creation path which is already resolved by
switching to an ordered workqueue (it'd probably be better to use
per-cpu wq w/ @max_active == 1 tho).  This patchset is about relesae
path.  slab_mutex contention would definitely go down with this but
I don't think there's more connection to it than that.

Thanks.
