Subject: [PATCH v3 12/19] ovl: handle idmappings for layer fileattrs
Date: Thu, 31 Mar 2022 13:23:10 +0200 [thread overview]
Message-ID: <20220331112318.1377494-13-brauner@kernel.org> (raw)
In-Reply-To: <20220331112318.1377494-1-brauner@kernel.org>
Take the upper mount's idmapping into account when setting fileattrs on
the upper layer. This is needed to support idmapped base layers with
overlay.
