Subject: [PATCH] cpu_kill/cpu_die coordination
Date: Sat, 6 Apr 2013 15:37:03 +0300 [thread overview]
Message-ID: <1365251824-4852-1-git-send-email-kevin@bracey.fi> (raw)
I've been having problems handshaking between cpu_kill and cpu_die, due to the
fact that they don't always occur together. It seems to me that this patch is
basically what's needed. I'm working on 3.4-based code, but the logic doesn't
seem to have changed since then.
Searches didn't show much activity in this area - it appears that I'm on the
only upstream platform actually implementing cpu_kill, which may explain why
it's not been noticed.
Only related topic I found was this discussion:
https://patchwork.kernel.org/patch/1898311/
which could maybe be short-circuited by this patch.
