From ba8adad5d036733d240fa8a8f4d055f3d4490562 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 21 Feb 2020 08:31:27 -0800 Subject: xfs: remove the kuid/kgid conversion wrappers Remove the XFS wrappers for converting from and to the kuid/kgid types. Mostly this means switching to VFS i_{u,g}id_{read,write} helpers, but in a few spots the calls to the conversion functions is open coded. To match the use of sb->s_user_ns in the helpers and other file systems, sb->s_user_ns is also used in the quota code. The ACL code already does the conversion in a grotty layering violation in the VFS xattr code, so it keeps using init_user_ns for the identity mapping.
