Subject: [PATCH 01/24] bsg: remove support for SCSI_IOCTL_SEND_COMMAND
Date: Mon, 12 Jul 2021 07:47:53 +0200	[thread overview]
Message-ID: <20210712054816.4147559-2-hch@lst.de> (raw)
In-Reply-To: <20210712054816.4147559-1-hch@lst.de>

SCSI_IOCTL_SEND_COMMAND has been deprecated longer than bsg exists
and has been warning for just as long.  More importantly it harcodes
SCSI CDBs and thus will do the wrong thing on non-scsi bsg nodes.

Fixes: aa387cc89567 ("block: add bsg helper library")
Signed-off-by: Christoph Hellwig <hch@lst.de>
