[PATCH v2 0/9] block: Consolidate scsi sense buffer usage

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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 1/9] ide-cd: Drop unused sense buffers
 [PATCH 2/9] scsi: cxlflash: Drop unused sense buffers

Next, allow the sense buffer to be usable outside SCSI tree:
 [PATCH 3/9] scsi: build scsi_common.o for all scsi passthrough request users
 [PATCH 4/9] target: don't depend on SCSI

Then move all request_sense usage to scsi_sense_hdr:
 [PATCH 5/9] block: Switch struct packet_command to use struct scsi_sense_hdr

And do some further cleanups for scsi_sense_hdr now that we can:
 [PATCH 6/9] ide-cd: Remove redundant sense buffer
 [PATCH 7/9] cdrom: Use struct scsi_sense_hdr internally

Finally add a build-time check to make sure we don't pass bad buffer sizes:
 [PATCH 8/9] libata-scsi: Move sense buffers onto stack
 [PATCH 9/9] scsi: Check sense buffer size at build time
