Hi backport forks,
I was trying to fix ckmake FAIL building against 4.9 for 4.9.297+.
I found that macro KERNEL_VERSION_IN_RANGE(4,9,297, 4,10,0) won't work
because SUBLEVEL 297 had overflowed 4 bit (255) in KERNEL_VERSION.
How are we supposed to deal with such situation?
Hm. I guess the only way would be to somehow make a Kconfig variable in
backports, that uses the Makefile settings? But env="SUBLEVEL" doesn't
work, so not sure, maybe some Makefile trickery to extract it and write
it to the config?
Or is it possible to persuade stable forks to define LINUX_VERSION_SUBLEVEL
on existing stable releases?
Or just find a way to handle the specific area? Is this for the
build_bug.h stuff?
Yes, any idea?
Thanks.
