This is a follow-up to commit f7068114d45e ("sr: pass down correctly sized SCSI sense buffer") which further cleans up and removes needless sense character array buffers and "struct request_sense" usage in favor of the common "struct scsi_sense_hdr". First, drop a bunch of unused sense buffers: [PATCH 1/6] ide-cd: Drop unused sense buffers [PATCH 2/6] scsi: cxlflash: Drop unused sense buffers Next, split out struct scsi_sense_hdr: [PATCH 3/6] block: Create scsi_sense.h for SCSI and ATAPI Then move all request_sense usage to scsi_sense_hdr: [PATCH 4/6] block: Consolidate scsi sense buffer usage Finally add a build-time check to make sure we don't pass bad buffer sizes: [PATCH 5/6] libata-scsi: Move sense buffers onto stack [PATCH 6/6] scsi: Check sense buffer size at build time -Kees
