Ming Lei 68afb02d21 block: check bio alignment in blk_mq_submit_bio ... commit 0676c434a9 upstream. IO logical block size is one fundamental queue limit, and every IO has to be aligned with logical block size because our bio split can't deal with unaligned bio. The check has to be done with queue usage counter grabbed because device reconfiguration may change logical block size, and we can prevent the reconfiguration from happening by holding queue usage counter. logical_block_size stays in the 1st cache line of queue_limits, and this cache line is always fetched in fast path via bio_may_exceed_limits(), so IO perf won't be affected by this check.
