Looks like, 9223372036854775807 is just LLONG_MAX.
I can not reproduce that (on openSUSE 11.1). I also don't see
the _llseek() calls.
weird. no btrfs issue then !?

This is with today's git kernel and today's standalone btrfs unstable.
You are using the distro kernel and compile the standalone btrfs module?
yes.
to be honest, i`m slightly newer than 11.1 (did zypper dup to latest factory
some days ago)
