  "message": "nbd: add locking to nbd_ioctl\n\nThe code was written to rely on big kernel lock to protect it from races.\nIt mostly works when interface is not abused.\n\nSo this uses tx_lock to protect data structures from concurrent use\nbetween ioctl and worker threads.\n\nNext step will be moving from ioctl to unlocked_ioctl.\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: add missing return]\nSigned-off-by: Pavel Machek \u003cpavel@suse.cz\u003e\nAcked-by: Paul Clements \u003cpaul.clements@steeleye.com\u003e\nCc: Jens Axboe \u003cjens.axboe@oracle.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
