From 5cb81dabcc28863e7d04e6fd9ede154bd8459c14 Mon Sep 17 00:00:00 2001 From: Dmitry Monakhov Date: Sat, 29 Oct 2011 09:05:00 -0400 Subject: ext4: fix quota accounting during migration The tmp_inode should have same uid/gid as the original inode. Otherwise new metadata blocks will be accounted to wrong quota-id, which will result in a quota leak after the inode migration is completed.
