Ooh, it isn't in mainline yet but pulling rcu tree will cause a silent
conflict with this pull request which leads to build failure. The two
colliding commits are.
5b95e1af8d17 ("workqueue: wq_pool_mutex protects the attrs-installation")
eeacf8982637 ("rcu: Rename rcu_lockdep_assert() to RCU_LOCKDEP_WARN()")
The former adds rcu_lockdep_assert() usage and the latter renames and
flips it. It can be resolved by renaming and negating the conditions
in the new usage.
Thanks.
