From b5a08423da9da59c7f38ed8dbb6dd6cbbe9024a4 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Tue, 2 Mar 2021 09:32:52 -0800 Subject: xfs: fix quota accounting when a mount is idmapped Nowadays, we indirectly use the idmap-aware helper functions in the VFS to set the initial uid and gid of a file being created. Unfortunately, we didn't convert the quota code, which means we attach the wrong dquots to files created on an idmapped mount.
