Adrian, you must be misunderstanding something. Where exactly in the 
above sentences do i assert that you "knew about this bug before the 
feature hit mainline"? I dont say that and cannot say that - and it's 
rather irrelevant. All i say is that you knew about this bug for a long 
time.

i mean you send tons of trivial patches along the lines of:

|  Author: Adrian Bunk <bunk@...nel.org>
|  Date:   Fri Feb 22 21:58:37 2008 +0200
|
|    x86: don't make swapper_pg_pmd global

to reduce size of the kernel. At 50 bytes of image savings a pop, the 
127,000 bytes savings my patch gives would be equivalent to more than 
2500 of such patches of yours.

In other words: you knew about a bug that would have the same kernel 
image size reduction equivalent to 2500 of your own tiny patches. Still 
you didnt feel the need to pursue the issue?

I'm not sure about you, but that sure looks weird to me, and i'm really 
curious what your interpretation of it is. (which, AFAICS, you have not 
offered so far. You have rejected my common-sense explanation of your 
actions rather forcefully, so logically there must be some other 
explanation.)
