Subject: [PATCH 02/12] kvm: use __anon_inode_getfd
Date: Fri,  8 May 2020 17:36:24 +0200	[thread overview]
Message-ID: <20200508153634.249933-3-hch@lst.de> (raw)
In-Reply-To: <20200508153634.249933-1-hch@lst.de>

Use __anon_inode_getfd instead of opencoding the logic using
get_unused_fd_flags + anon_inode_getfile.
