Subject: [PATCH v2 06/13] udmabuf: add MEMFD_CREATE dependency
Date: Tue, 11 Sep 2018 15:42:09 +0200	[thread overview]
Message-ID: <20180911134216.9760-7-kraxel@redhat.com> (raw)
In-Reply-To: <20180911134216.9760-1-kraxel@redhat.com>

udmabuf builds without it, but if userspace can not create memfd
handles in the first place it is rather pointless to include it,
except for test builds.
