This replaces the checkpatch patches in my series arch: barrier cleanup + barriers for virt and will be included in the pull request including the series. changes from v3: rename smp_barrier_stems to barrier_stems as suggested by Julian Calaby. add (?: ... ) around a variable in regexp, in case we change the value later so that it matters. changes from v2: address comments by Joe Perches: use (?: ... ) to avoid unnecessary capture groups rename smp_barriers to smp_barrier_stems for clarity add barriers before/after atomic Changes from v1: catch optional\s* before () in barriers rewrite using qr{} instead of map Michael S.
