[PATCH 0/4] Final ACCESS_ONCE() cleanups for v4.15

From: Mark Rutland
Date: Mon Nov 27 2017 - 05:38:35 EST


Now that the ACCESS_ONCE() conversion settled in v4.15-rc1, these
patches remove the ACCESS_ONCE() definitions from the kernel, along with
the newly redundant checkpatch warning suggesting {READ,WRITE}_ONCE()
are preferred.

One new user of ACCESS_ONCE() snuck into v4.15-rc1; the first patch in
this series (previously sent on its own [1]) moves that over to
READ_ONCE(). Otherwise, there are no remaining uses of ACCESS_ONCE().

Ingo, assuming there are no complaints, would you be happy to take this
via the tip tree as a fixup for v4.15?

I've also pushed the series to my core/access-once-removal branch [2].

Thanks,
Mark.
