Multiple filesystems take uid and gid as options, and the code to create the ID from an integer and validate it is standard boilerplate that can be moved into common helper functions, so do that for consistency and less cut&paste. This also helps avoid the buggy pattern noted by Seth Jenkins at https://lore.kernel.org/lkml/CALxfFW4BXhEwxR0Q5LSkg-8Vb4r2MONKCcUCVioehXQKr35eHg@xxxxxxxxxxxxxx/ because uid/gid parsing will fail before any assignment in most filesystems. Net effect is a bit of code removal, as well. Patch 1 is the infrastructure change, then per-fs conversions follow, cc'd as appropriate.
