Subject: Re: [RFC PATCH 1/6] bsg: fix kernel panic resulting from missing allocation of a reply-buffer
Date: Thu, 10 Aug 2017 11:32:17 +0200 [thread overview]
Message-ID: <20170810093217.GL24539@lst.de> (raw)
In-Reply-To: <9e67ce3fc2f3cd42e9e05b2753b00d6676f46ee1.1502120928.git.bblock-23VcF4HTsmIX0ybBhKVfKdBPR1lH4CV8@public.gmane.org>
We can't use an on-stack buffer for the sense data, as drivers will
dma to it. So we should reuse the SCSI init_rq_fn() for the BSG
queues and/or implement the same scheme.
