Hi, 1 gets rid of the dummy nop profile, 2 marks the queue as having an actual profile, and 3 avoids calling into bio_integrity_prep() if we don't have a profile. This both reduces code (getting rid of the nop profile) and reduces the overhead of the standard setup of having integrity enabled in kconfig, yet not using a device with an integrity profile. block/blk-integrity.c | 38 ++++++++++---------------------------- block/blk-mq.c | 11 +++++++---- include/linux/blkdev.h | 1 + 3 files changed, 18 insertions(+), 32 deletions(-) -- Jens Axboe
