  "message": "rds: rcu-ize rds_ib_get_device()\n\nrds_ib_get_device is called very often as we turn an\nip address into a corresponding device structure.  It currently\ntake a global spinlock as it walks different lists to find active\ndevices.\n\nThis commit changes the lists over to RCU, which isn\u0027t very complex\nbecause they are not updated very often at all.\n\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n",
