    U60, with lenny (and mainline kernel) on it. Probably ought to upgrade
    to squeeze one of those days... It works, all right, but it's only 2-way,
    so reproducing would probably be harder. Plus the fun of building the tests
    themselves on somewhat different userland...

    Anyway, I wonder why you care about __d_lookup_rcu() and ->d_inode stability;
    d_mountpoint() _is_ stable at that point (we hold vfsmount_lock) and you
    don't seem to look at ->d_inode at all in RCU case. Note that ->d_automount()
    is never called in RCU case at all; nor is ->lookup() and friends, so you
    really only have ->d_manage() to cope with, what with autofs4 having no
    ->d_revalidate() anymore.

    BTW, Nick has moved to kernel.dk; whether he's still reachable there is
    a question, though - he seems to have disappeared since mid-January.
