Linus Torvalds fed8f5090c Merge branch 'percpu_ref-rcu-audit-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc 
Pull percpu_ref rcu fixes from Tejun Heo:
 "Jann Horn found that aio was depending on the internal RCU grace
  periods of percpu-ref and that it's broken because aio uses regular
  RCU while percpu_ref uses sched-RCU.

  Depending on percpu_ref's internal grace periods isn't a good idea
  because

   - The RCU type might not match.

   - percpu_ref's grace periods are used to switch to atomic mode. They
     aren't between the last put and the invocation of the last release.
     This is easy to get confused about and can lead to subtle bugs.

   - percpu_ref might not have grace periods at all depending on its
     current operation mode.

  This patchset audits and fixes percpu_ref users for their RCU usages"

[ There's a continuation of this series that clarifies percpu_ref
  documentation that the internal grace periods must not be depended
  upon, and introduces rcu_work to simplify bouncing to a workqueue
  after an RCU grace period.

  That will go in for 4.17 - this is just the minimal set with the fixes
  that are tagged for -stable ]
