Hi Linus,
I'm sending you a patch which fixes a bug in locking (we take one lock
twice) for old quota format. Without this patch the old format simply
don't work (I really don't know how that could happen). My thanks go to
Herbert Potzl who spotted it. The patch is attached, please apply.
Thanks
Honza
