[PATCH] lockdep: annotate sk_locks
Teach sk_lock semantics to the lock validator. In the softirq path the
slock has mutex_trylock()+mutex_unlock() semantics, in the process context
sock_lock() case it has mutex_lock()/mutex_unlock() semantics.
Thus we treat sock_owned_by_user() flagged areas as an exclusion area too,
not just those areas covered by a held sk_lock.slock.
Effect on non-lockdep kernels: minimal, sk_lock_sock_init() has been turned
into an inline function.
