Subject[RESEND PATCH v4 00/10] Rework REFCOUNT_FULL using atomic_fetch_* operations
Date
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
