Hi,
inspired by the mail http://lkml.org/lkml/2009/2/15/159
I did
grep -Ern '\!=.*\|\|.*\!=' linux-2.6.28.5
and found the following tests which are always true if the tested variable is
not NaN:
linux-2.6.28.5/sound/pci/au88x0/au88x0_core.c:2792: if ((bits != 8) || (bits != 16))
linux-2.6.28.5/sound/oss/ad1848.c:283: if ( (devc->model != MD_1845) ||
(devc->model != MD_1845_SSCAPE))

devc->model != MD_1845_SSCAPE)

linux-2.6.28.5/drivers/block/paride/pf.c:569: if ((buf[k + offs] != 0x20) ||

already known:

word0 != MAGIC) {

read only, all 1's */
