Subject: [PATCH 0/6] block: Consolidate scsi sense buffer usage

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
