2.1.131 here shows same problem, btw the only stuff to be accessing
/home is this one. I am running knfsd-981204 (though I didn't patch
the kernel with HJ's patches, as I only use kNFS on my home ethernet
and it works fine without patching the kernel).

/home has the problem, / is fine. fuser'ing root shows only normal stuff:

[asuardi@dogbert asuardi]$ fuser -v /

USER PID ACCESS COMMAND
/ asuardi 335 .r... bash
asuardi 353 .r... startx
asuardi 354 .r... xinit
asuardi 357 .r... sh
asuardi 359 .r... fvwm2
asuardi 363 .r... FvwmButtons
asuardi 364 .r... FvwmTaskBar
asuardi 367 .r... xclock
asuardi 368 .r... FvwmPager
asuardi 371 .r... xlock
asuardi 374 .r... bash
asuardi 387 .r... bash
asuardi 419 .r... netscape-commun
asuardi 431 .r... netscape-commun
asuardi 494 .r... bash
asuardi 525 .r... fuser

while /home has this one:

[asuardi@dogbert asuardi]$ fuser -v /home

USER PID ACCESS COMMAND
/home root kernel mount /home
[asuardi@dogbert asuardi]$

(which isn't going away after stopping the kNFS processes).
