Subject: [PATCH] xfs: remove the icdinode di_uid/di_gid members
Git-commit: 542951592c99ff7b15c050954c051dd6dd6c0f97
Patch-mainline: v5.7-rc1
References: bsc#1190006
Use the Linux inode i_uid/i_gid members everywhere and just convert
from/to the scalar value when reading or writing the on-disk inode.
