Subject: [dm-devel] [PATCH 20/35] multipathd: move uxsock_trigger() to uxlsnr.c
Date: Fri, 10 Sep 2021 13:41:05 +0200 [thread overview]
Message-ID: <20210910114120.13665-21-mwilck@suse.com> (raw)
In-Reply-To: <20210910114120.13665-1-mwilck@suse.com>
From: Martin Wilck <mwilck@suse.com>
uxsock_trigger() really belongs into cli.c. I suppose that way back in
the past there were strong reasons to call this function via a
pointer. I don't think these reasons are valid any more. Moving
the function to cli.c allows restructuring the code.
No functional changes.
