[PATCH 1/2] blktrace: use cmpxchg
Replace open-coded racy implementation of cmpxchg with the real thing. This bug is probably easy to maliciously trigger from userspace, and I think it will result in memory corruption, but the race window is small so I think it's unlikely to be triggered accidentally.

[PATCH 0/2] blktrace: startup / shutdown race fixes
I ran into the stale-block-directory problem while using blktrace, and while chasing it noticed the open-coded cmpxchg. The unlink-on-final-close is a longstanding bug that's triggerable by the standard blktrace(1) utility (it races child threads against the parent), and should go to -stable. The cmpxchg is a st... 15 Jul 2010 14:17
