Multiple & vs. && and | vs. || bugs in 2.4 and 2.5

[Norbert Kiesel <nkiesel@tbdnetworks.com>]

Hi,
inspired by the recent bug report from Muli Ben-Yehuda (see
http://marc.theaimsgroup.com/?l=linux-kernel&m=104647477025930), I
hunted for similar bugs in 2.4 and 2.5 using a simple grep:

find ${1:-.} -name \*.c | xargs grep -En '![a-zA-Z0-9_ ]+(\|[^|]|\&[^&])|([^|]\||[^&]\&) *!'

This found typos in both 2.4.20 and 2.5.63.  Please note that is a
trimmed down list of the grep, I removed what I considered false
positives (e.g. real bit operations and matches within comments).  All
but the trident.c typo looks like a logical and not a bit operation to
me.

linux-2.5.63/mm/slab.c:1646:		if (!flags & __GFP_WAIT)

Should I create patches for these and send them to the maintainers?

so long
