Subject: [PATCH 0/2 -rt] make locckdep selftest work on -rt
Date: Mon, 16 Apr 2012 15:01:54 +0800 [thread overview]
Message-ID: <1334559716-18447-1-git-send-email-yong.zhang0@gmail.com> (raw)
On -rt,
1) There is no softirq context any more;
2) rwlock can not be used in harirq context;
Wrt that, convert spinlock to raw spinlock to make spinlock+hardirq
work, and discard the test for rwlock+hardirq and softirq.
BTW, I think patch#1 can go to upstream.
Thanks,
Yong
