Subject: [PATCH v4 05/21] btrfs/inode: allow idmapped mknod iop
Date: Tue, 27 Jul 2021 12:48:44 +0200 [thread overview]
Message-ID: <20210727104900.829215-6-brauner@kernel.org> (raw)
In-Reply-To: <20210727104900.829215-1-brauner@kernel.org>
From: Christian Brauner <christian.brauner@ubuntu.com>
Enable btrfs_mknod() to handle idmapped mounts. This is just a matter of
passing down the mount's userns.
