I was talking about the vmlinux file, and probably should have said
bzImage size, which has 14 KB increase when CET is enabled.
Well, vmlinux size is important too. 1 page of vmlinux size means one
fewer page of memory available for real use.
I would really encourage you when you write to try to be specific and
use as much plain language as possible without being verbose. Most
people understand things like "this feature increases kernel text size".
I wouldn't expect most folks who can type "make oldconfig; make
install" to understands the difference between vmlinux and bzImage.
Ok, thanks!
