Let's be clear, I just collect patches that I think are interesting. The original post by Andrew Morton <akpm@digeo.com> is here:
http://marc.theaimsgroup.com/?l=linux-kernel&m=104695003008386&w=2
Quoting it:
shrinks my 3.2.1-compiled kernel text by about 64 kbytes:
text data bss dec hex filename 3316138 574844 726816 4617798 467646 vmlinux-before 3249255 555436 727204 4531895 4526b7 vmlinux-after
mnm:/tmp> nm vmlinux-before|grep __constant_c_and_count_memset | wc 233 699 9553 mnm:/tmp> nm vmlinux-after|grep __constant_c_and_count_memset | wc 13 39 533
And I also remember other posts, by other author of a similar patch, that claimed some critical functions not being inlined due to size (memcpys..). Will try to look original info about that... ...here it is:
