From: Tahsin Erdogan Date: Thu, 22 Jun 2017 01:27:00 +0000 (-0400) Subject: ext4: ea_inode owner should be the same as the inode owner X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9e1ba00161a6f3bec8d4e7912025cbf889878e59;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ext4: ea_inode owner should be the same as the inode owner Quota charging is based on the ownership of the inode. Currently, the xattr inode owner is set to the caller which may be different from the parent inode owner. This is inconsistent with how quota is charged for xattr block and regular data block writes.
