From: Yong Zhang <yong.zhang@windriver.com>
This is inspired by http://lkml.org/lkml/2010/8/16/291 which catch a lockdep false positive on fake_timer_lock. When I go into del_timer_sync(), but don't find anything which prevent del_timer_sync() from using in softirq context, and indeed it's been used in softirq for some timer(such as __dst_free()).
Thus, tell others it can't be used in softirq context, and teach lockdep about that. It's realized by patch-0002.
Your comments are very appreciated.
Thanks, Yong
