Subject: [RESEND PATCH v4 00/10] Rework REFCOUNT_FULL using atomic_fetch_* operations
Date: Thu, 21 Nov 2019 11:58:52 +0000 [thread overview]
Message-ID: <20191121115902.2551-1-will@kernel.org> (raw)
Hi everybody,
This is a resend of version four of the patches I posted here:
v4: https://lore.kernel.org/lkml/20191030143035.19440-1-will@kernel.org
Previous versions can be found at:
v1: https://lkml.kernel.org/r/20190802101000.12958-1-will@kernel.org
v2: https://lkml.kernel.org/r/20190827163204.29903-1-will@kernel.org
v3: https://lkml.kernel.org/r/20191007154703.5574-1-will@kernel.org
I didn't receive any feedback last time around, other than some positive
noises from Kees, so please consider this for inclusion in mainline.
Thanks,
Will
