Hi all,
It seems the problem was that the reiserfs filesystem was mounted without explicitly enabling xattrs. As Bertl explained
on IRC:
"<Bertl> i.e. the attributes are cached as long as the inode stays in memory"
thus we could see the barrier enabled until umount/reboot.
So mounting it with attrs resolved the issue on latest kernel + patest patch + latest utils.
Cheers,
- -Nik
