fasync: Fix deadlock between task-context and interrupt-context kill_fasync() (2018-05-01 07:39:50 -0400)
----------------------------------------------------------------
Just a single fix for a deadlock in the fasync handling code that Kirill
observed while testing. The fix is to change the fa_lock to be rwlock_t,
and use a read lock in kill_fasync_rcu.
