[PATCH] wireless extensions should default to Y

[PATCH] wireless extensions should default to Y

[Pavel Machek]

Do we need following patch on top of
24a0aa212ee2dbe44360288684478d76a8e20a0a revert?

I updated kernel today, and (probably because extensions were not
selectable before), the default choice was "N", which is wrong:
oldconfig should result in compatible choices being made, for example
to help bisect.

I don't believe we need this. It has been defaulting to N for a long
time, it's just that it got thrown out of your config due to building
inbetween the patch and its revert. Had you built only before and after
that wouldn't be an issue.

If we default to Y now we send the wrong signal. If you really need to
bisect something wext related you have far bigger issues I'd think, the
code hasn't changed *forever*.

Well, I clearly hit the issue. If someone had _not_ build in between,
the "default y" does not change anything for him, as he will not be
asked thequestion. If someone starts config from scratch, Y is the
safe answer.

I am woried about bisecting something unrelated, and then wext coming
and breaking the bisect. But you are right that it will break the
bisect, anyway...

We've long stated that if really starting from scratch it's the wrong
thing to do and had a default N, so I don't really know why we'd revert
that only to make a short period of bisect slightly happier?

I really don't want to merge this patch and encourage more people to
build with wext enabled.
