To me, the important bit was "drives me bats when I merge a patch but have
to jump through a series of hoops ..."

And "we really should optimise things" does not mean that your patch is an
ideal solution. You make users' life a bit easier (maybe), but miserable
for me. As I read Andrew, a better solution have to be implemented (e.g.
CONFIG_AKPM, which I didn't find being too sarcastic :-), which would suit
both users and maintainers.

Btw, I am a Linux user too. And the amount of Kconfig symbols never ever
bothered me personally. Why? Look:

	~$ grep CONFIG /boot/config-3.8.0-28-desktop  | wc -l
	5274

Do you think that even if you divide this by two it would make any
difference? Not to me. When dealing with these large sets of options, my
strategy of making configs is different (as I explained previous emails it
is either '{old,allmod}config'+tuning or 'allnoconfig'+deliberately
enabling options for specific hardware/needs.

Don't take it personally, but for me the patch does not do anything good
at all. And again, feel free to send it to akpm with my nack and a link,
since I might be still wrong.

Cheers,

Anton
