Subject: [PATCH 09/15] aacraid: don't bother with setting SCp.Status
Date: Thu, 25 Nov 2021 16:10:42 +0100 [thread overview]
Message-ID: <20211125151048.103910-10-hare@suse.de> (raw)
In-Reply-To: <20211125151048.103910-1-hare@suse.de>
SCp.Status is only ever evaluated to set the return code of
aac_probe_container(), and all callers only check for negative
values here. The callbacks set it to the value of aac_mount.count,
which is an unsigned int; as such it should never become negative
here, and so we only need to return an error from aac_probe_container()
if we can't send the initial fib. But once that's done we can return
'0' and don't need to set SCp.Status at all.
