Message-ID: <20230412042624.600511-4-chandan.babu@xxxxxxxxxx>
From: Christoph Hellwig <hch@xxxxxx>
commit 3d8f2821502d0b60bac2789d0bea951fda61de0c upstream.
Instead of only synchronizing the uid/gid values in xfs_setup_inode,
ensure that they always match to prepare for removing the icdinode
fields.
