From 209188ce75d0d357c292f6bb81d712acdd4e7db7 Mon Sep 17 00:00:00 2001 From: Christian Brauner Date: Fri, 3 Dec 2021 12:17:05 +0100 Subject: fs: port higher-level mapping helpers Enable the mapped_fs{g,u}id() helpers to support filesystems mounted with an idmapping. Apart from core mapping helpers that use mapped_fs{g,u}id() to initialize struct inode's i_{g,u}id fields xfs is the only place that uses these low-level helpers directly. The patch only extends the helpers to be able to take the filesystem idmapping into account. Since we don't actually yet pass the filesystem's idmapping in no functional changes happen. This will happen in a final patch.
