That might be vfsmount being dropped when it shouldn't or dentry leaked. And seeing that it's umount(8), I would suspect the latter...
Anyway, with the latest from dhowells we probably should have d_set_d_op() mess on autofs4 under control (in #for-next). Whether it's enough to actually fix the sucker is a separate question, of course - there might very well be more crap.
I've instrumented mntput() et.al. here; hopefully that'll make catching the remaining turds easier. As for dcache leaks... ouch. Could you try to reproduce that one on the mainline kernel? At least that'd isolate things a bit.
