I'm not on intel-gfx and for some reason these patches didn't show up on
linux-mm.  I wanted to comment on "mutex: Export an interface to wrap a
mutex lock" but
http://lists.freedesktop.org/archives/intel-gfx/2015-April/064063.html
doesn't tell me which mailing lists were cc'ed and I can't find that
patch on linux-kernel.

Can you please do something to make this easier for us??

And please fully document all the mutex interfaces which you just
added.
