Subject: [PATCH v2 09/21] btrfs/inode: allow idmapped tmpfile iop
Date: Mon, 19 Jul 2021 13:10:40 +0200	[thread overview]
Message-ID: <20210719111052.1626299-10-brauner@kernel.org> (raw)
In-Reply-To: <20210719111052.1626299-1-brauner@kernel.org>

From: Christian Brauner <christian.brauner@ubuntu.com>

Enable btrfs_tmpfile() to handle idmapped mounts. This is just a matter of
passing down the mount's userns.
