.SH "DESCRIPTION"
.PP
Keep every historical prep hook as its own optional alias so RHEL8\-era 4\&.18 still matches, while newer kernels use the blk\-mq names: \- scsi_prep_fn / sd_prep_fn / sr_prep_fn: request_fn blk_queue_prep_rq (v4\&.18/4\&.19; gone by v5\&.0) \- scsi_mq_prep_fn: early blk\-mq prep (v4\&.18 through ~6\&.x) \- scsi_prepare_cmd: current name (renamed from scsi_mq_prep_fn)
