Subject: [PATCH 0/8] stop_machine: stop_one_cpu_nowait() fix, misc cleanups
Date: Sun, 15 Nov 2015 20:32:54 +0100	[thread overview]
Message-ID: <20151115193254.GA8225@redhat.com> (raw)

Hello,

I tried to backport the recent stop_machine fixes and recalled that
I forgot to make the fix and cleanups I promised during the previous
discussion.

Please review.

I am also going to rediff/resend my old patch which removes lglock
from stop_machine.c, but it probably needs more discussion so I'll
send it separately.

Oleg.
