The ext3 root inode was treated specially with respect to in-inode extended attributes, for reasons detailed in the removed comment below. The first mkfs-created inodes would not get extra_i_size or the EXT3_STATE_XATTR flag set in ext3_read_inode, which disallowed reading or setting in-inode EAs on the root. However, in ext4, ext4_mark_inode_dirty calls ext4_expand_extra_isize for all inodes; once this is done EAs may be placed in the root ext4 inode body. But for reasons above, it won't be found after a reboot. testcase: setfattr -n user.name -v value mntpt/ setfattr -n user.name2 -v value2 mntpt/ umount mntpt/; remount mntpt/ getfattr -d mntpt/ name2/value2 has gone missing; debugfs shows it in the inode body, but it is not found there by getattr. The following fixes it up; newer mkfs appears to properly zero the inodes, so this workaround isn't needed for ext4.
