From fd7048adb7a5f3c44154675e0e128fe0f2e16bef Mon Sep 17 00:00:00 2001 From: Mark Rutland Date: Mon, 23 Oct 2017 14:07:15 -0700 Subject: locking/atomics, fs/ncpfs: Convert ACCESS_ONCE() to READ_ONCE()/WRITE_ONCE() The NCPFS code has some stale comments regarding ACCESS_ONCE() uses which were removed a long time ago.
