+Subject: [PATCH] sched/wait: Fix add_wait_queue() behavioral change
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The following cleanup commit:
+
+  50816c48997a ("sched/wait: Standardize internal naming of wait-queue entries")
+
+... unintentionally changed the behavior of add_wait_queue() from
+inserting the wait entry at the head of the wait queue to the tail
+of the wait queue.
+
+Beyond a negative performance impact this change in behavior
+theoretically also breaks wait queues which mix exclusive and
+non-exclusive waiters, as non-exclusive waiters will not be
+woken up if they are queued behind enough exclusive waiters.
