[PATCH] kyber: fix another domain token wait queue hang

2017-12-04 Thread Omar Sandoval
From: Omar Sandoval Commit 8cf466602028 ("kyber: fix hang on domain token wait queue") fixed a hang caused by leaving wait entries on the domain token wait queue after the __sbitmap_queue_get() retry succeeded, making that wait entry a "dud" which won't in turn wake more entries
