Subject: [PATCH 14/24] btrfs/inode: allow idmapped permission iop
Date: Tue, 13 Jul 2021 13:13:34 +0200 [thread overview]
Message-ID: <20210713111344.1149376-15-brauner@kernel.org> (raw)
In-Reply-To: <20210713111344.1149376-1-brauner@kernel.org>
From: Christian Brauner <christian.brauner@ubuntu.com>
Enable btrfs_permission() to handle idmapped mounts. This is just a matter of
passing down the mount's userns.
