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.
