  "message": "shared tag queue barrier comment\n\nShould add some comments for the tag barriers (they won\u0027t be so important\nif we can switch over to the explicit _lock bitops, but for now we should\nmake it clear).\n\nJens\u0027 original patch said a barrier after the test_and_clear_bit was also\nrequired. I can\u0027t see why (and it would prevent the use of the _lock bitop).\n\nAcked-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n--\n",
