I have no half-way relevant test-case for this, so I'm hoping people who have good VFS stress-tests (preferably under memory pressure so that we get that whole shrinking path) will test.
But it looks fine.
That said, I do hate that RCU read-lock around the final spin-unlock.
Let me go talk to the paravirt people. Maybe they don't need this, and I don't know exactly *how* they use that lock pointer after the unlock in the "kick waiters" part. Maybe it's all good.
