Hi all, this is my version of Damien's "Fix queue freeze and limit locking order". A lot looks very similar, but it was done independently based on the previous discussion. Changes since RFC: - fix a bizzare virtio_blk bisection snafu - set BLK_FEAT_POLL a little less eagerly for blk-mq - drop the loop patch just adding a comment - improve various commit logs and coments Diffstat: block/blk-core.c | 17 ++++- block/blk-integrity.c | 4 - block/blk-mq.c | 17 ----- block/blk-settings.c | 27 ++++++++ block/blk-sysfs.c | 128 +++++++++++++++++++---------------------- block/blk-zoned.c | 7 -- drivers/block/nbd.c | 17 ----- drivers/block/virtio_blk.c | 4 - drivers/nvme/host/core.c | 9 +- drivers/scsi/sd.c | 17 +---- drivers/scsi/sr.c | 5 - drivers/usb/storage/scsiglue.c | 5 - include/linux/blkdev.h | 5 - 13 files changed, 123 insertions(+), 139 deletions(-)
