Request for 3.18-stable: a63b03e2d247 ("mutex: Always clear owner field upon mutex_unlock()")

Hi Greg,

I noticed that 3.18.125 added commit bc07ee33284a ('Revert "drm/i915: Fix mutex->owner inspection race under DEBUG_MUTEXES"'), which states that the reason it can be applied is:

The core fix was applied in

commit a63b03e2d2477586440741677ecac45bcf28d7b1 Author: Chris Wilson chris@chris-wilson.co.uk Date: Tue Jan 6 10:29:35 2015 +0000

mutex: Always clear owner field upon mutex_unlock()

(note the absence of stable@ tag)

so we can now revert our band-aid commit 226e5ae9e5f910 for -next.

but that the commit referenced wasn't also pulled in.

Please consider pulling that one too if you're going to do another 3.18 stable release.

Thanks,

Tom
