Very nice. Happy it worked (partially).

The readlink system call should work, but I see the readlinkat system
call doesn't have a fuse marker in the valgrind PRE handler. I found
several other (at) syscalls missing the fuse marker so I filed a bug
and submitted a patch: https://bugs.kde.org/show_bug.cgi?id=493454

Cheers,
