So, there are two reports: 1) missed C file; 2) possible missed prototype. To solve 1) you need to add the C file to the patch. To solve 2) you need either declare it static or put it into the header file (I haven't checked deeply which one is your case). > > But my problem is that I cannot reproduce the issue found by the bot: > > the compiler that is downloaded by the script doesn't run on my build > > box because it wants a newer libc (I was hoping that those compilers > > were statically linked, but they aren't), while any other attempt I > > did with other older compilers resulted in either successful build or > > failed with other weird, apparently unrelated, errors about relocation > > issues (of course I tried with the arch and config used by the build > > bot). You may use compilers from kernel.org that don't require any libc at all (only good for kernel compilation). > > Is there any build farm publicly available or something like that?
