  "message": "ipc/sem.c: bugfix for semop() not reporting successful operation\n\nThe last change to improve the scalability moved the actual wake-up out of\nthe section that is protected by spin_lock(sma-\u003esem_perm.lock).\n\nThis means that IN_WAKEUP can be in queue.status even when the spinlock is\nacquired by the current task.  Thus the same loop that is performed when\nqueue.status is read without the spinlock acquired must be performed when\nthe spinlock is acquired.\n\nThanks to kamezawa.hiroyu@jp.fujitsu.com for noticing lack of the memory\nbarrier.\n\nAddresses https://bugzilla.kernel.org/show_bug.cgi?id\u003d16255\n\n[akpm@linux-foundation.org: clean up kerneldoc, checkpatch warning and whitespace]\nSigned-off-by: Manfred Spraul \u003cmanfred@colorfullife.com\u003e\nReported-by: Luca Tettamanti \u003ckronos.it@gmail.com\u003e\nTested-by: Luca Tettamanti \u003ckronos.it@gmail.com\u003e\nReported-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Maciej Rutecki \u003cmaciej.rutecki@gmail.com\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
