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. Signed-off-by: Tahsin Erdogan <tahsin@google.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
