Hello, The 1st patch removes blk_freeze_queue(). The 2nd & 3rd patches add blk_mq_freeze_queue_non_owner() and apply it on rbd. The 4th patches fixes potential unfreeze lock verification on non-owner context. The 5th patch doesn't verify io lock in elevator_init_mq() for fixing false lockdep warning. Ming Lei (5): block: remove blk_freeze_queue() blk-mq: add non_owner variant of blk_mq_freeze_queue API rbd: convert to blk_mq_freeze_queue_non_owner block: always verify unfreeze lock on the owner task block: don't verify IO lock for freeze/unfreeze in elevator_init_mq() block/blk-core.c | 2 +- block/blk-mq.c | 98 ++++++++++++++++++++++++++++-------------- block/blk.h | 4 +- block/elevator.c | 8 +++- drivers/block/rbd.c | 2 +- include/linux/blk-mq.h | 1 + include/linux/blkdev.h | 4 ++ 7 files changed, 81 insertions(+), 38 deletions(-) -- 2.47.0
