Subject: [PATCH 2/2] libs/devicemodel: add dm_op support for FreeBSD
Date: Tue,  5 Jan 2021 11:25:46 +0100	[thread overview]
Message-ID: <20210105102546.88462-3-roger.pau@citrix.com> (raw)
In-Reply-To: <20210105102546.88462-1-roger.pau@citrix.com>

The FreeBSD ioctls have the same fields has the Linux ones, so the
same file can be shared between both OSes.

No functional change for OSes different than FreeBSD.
