  "message": "[PATCH] aio: revert lock_kiocb()\n\nlock_kiocb() was introduced to serialize retrying and cancellation.  In the\nprocess of doing so it tried to sleep waiting for KIF_LOCKED while holding\nthe ctx_lock spinlock.  Recent fixes have ensured that multiple concurrent\nretries won\u0027t be attempted for a given iocb.  Cancel has other problems and\nhas no significant in-tree users that have been complaining about it.  So\nfor the immediate future we\u0027ll revert sleeping with the lock held and will\naddress proper cancellation and retry serialization in the future.\n\nSigned-off-by: Zach Brown \u003czach.brown@oracle.com\u003e\nAcked-by: Benjamin LaHaise \u003cbcrl@kvack.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
