Subject: [patch 0/4] DEBUG_RCU_HEAD: Debug and fix racy call_rcu() users

Here is a patchset, done on 2.6.30.9, which permits to detect and fix racy
call_rcu() users.

Fix for vunmap, which happens to be one of them, is included.

Note that some false-positives might come up when call_rcu() is called on
uninitialized struct rcu_head. The solution is, surprisingly enough, to
initialize them.

Thanks,

Mathieu
