That's not a bad idea. We could have a script that creates some kind

header file with #define HAVE_KTIME_GET_SECONDS and then we could use
that. We could even just do that for every single exported functions,
that will just be a few hundred lines but shouldn't matter much? :)
Ok maybe not - on a very small test configuration for me that's
actually something like 6.5k lines...
I guess then we could ship a list of functions we want to look at, like
a file that simply lists one function per line:
Basically the list would be the exported symbols from the backports
module, ie. compat.ko, right?
Gr. AvS
symbols-check:
ktime_get_seconds
<<<
and then we can do something like
grep -f symbols-check /path/to/Module.symvers | \
cut -f2 | \
tr 'a-z' 'A-Z' | \
sed 's/^/#define HAVE_/;s/$/ 1/' \
> backport-include/backport/existing-symbols.h
and include that in the right place?
