It wasn't specifically called out here, but yes, they were needed for the DAEMON fix. And they will be needed in the future probably as well because we have run into this problem many times when backporting patches (i.e. the backport throws tons of warnings because the min/max changes are not there.) Same for 6.1.y, which is why they are there too. > It's ok, but people are literally talking about this set of patches > causing a big slowdown in building the kernel, with some files going > from less than a second to build to being 15+ seconds because of the > preprocessor expansion they can cause. I saw that hopefully if that gets resolved in your tree we can backport the needed changes here tool. thanks, greg k-h
