From db998553cf11dd697485ac6142adbb35d21fff10 Mon Sep 17 00:00:00 2001 From: Christian Brauner Date: Sat, 20 Mar 2021 13:26:24 +0100 Subject: fs: introduce two inode i_{u,g}id initialization helpers Give filesystem two little helpers that do the right thing when initializing the i_uid and i_gid fields on idmapped and non-idmapped mounts. Filesystems shouldn't have to be concerned with too many details.
