Subject: remove QUEUE_FLAG_SCSI_PASSTHROUGH v2
Date: Tue, 19 Oct 2021 09:54:11 +0200 [thread overview]
Message-ID: <20211019075418.2332481-1-hch@lst.de> (raw)
Hi all,
this series removes the QUEUE_FLAG_SCSI_PASSTHROUGH and thus the last
remaining SCSI passthrough concept from the block layer.
The changes to support pktcdvd are a bit ugly, but I can't think of
anything better (except for removing the driver entirely).
If we'd want to support packet writing today it would probably live
entirely inside the sr driver.
Changes since v1:
- use an extra local variable in sd_get_unique_id to make sure we
always return the right length
- add an enum and a comment to better document ->get_unique_id
- spelling fixes
