  "message": "blk-throttle: Some cleanups and race fixes in limit  update code\n\nWhen throttle group limits are updated through cgroups, a thread is\nwoken up to process these updates. While reviewing that code, oleg noted\ncouple of race conditions existed in the code and he also suggested that\ncode can be simplified.\n\nThis patch fixes the races simplifies the code based on Oleg\u0027s suggestions:\n\n\t- Use xchg().\n\t- Introduced a common function throtl_update_blkio_group_common()\n          which is shared now by all iops/bps update functions.\n\nReviewed-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nReviewed-by: Paul E. McKenney \u003cpaulmck@linux.vnet.ibm.com\u003e\nSigned-off-by: Vivek Goyal \u003cvgoyal@redhat.com\u003e\n\nFixed a merge issue, throtl_schedule_delayed_work() takes throtl_data\nas the argument now, not the queue.\n\nSigned-off-by: Jens Axboe \u003cjaxboe@fusionio.com\u003e\n",
