Christoph Hellwig b0077e269f blk-mq: make sure active queue usage is held for bio_integrity_prep() ... blk_integrity_unregister() can come if queue usage counter isn't held for one bio with integrity prepared, so this request may be completed with calling profile->complete_fn, then kernel panic. Another constraint is that bio_integrity_prep() needs to be called before bio merge. Fix the issue by: - call bio_integrity_prep() with one queue usage counter grabbed reliably - call bio_integrity_prep() before bio merge Fixes: 900e080752 ("block: move queue enter logic into blk_mq_submit_bio()") Reported-by: Yi Zhang <yi.zhang@redhat.com> Cc: Christoph Hellwig <hch@lst.de> Signed-off-by: Ming Lei <ming.lei@redhat.com> Tested-by: Yi Zhang <yi.zhang@redhat.com> Link: https://lore.kernel.org/r/20231113035231.2708053-1-ming.lei@redhat.com Signed-off-by: Jens Axboe <axboe@kernel.dk>		2023-11-13 08:52:52 -07:00
