Re: [PATCH v3] selftests/mm: add process_madvise() tests

Hi Zi Yan,
Thanks for testing the patch and reporting this build failure.
I don't have an arm64 environment readily available for testing, so I
appreciate you catching this. I suspect this is caused by missing or
older userspace headers in the cross-compilation toolchain.
I will try to fix this in the next version. If the problem persists, a
good solution would be to manually define the syscall wrapper to avoid
the dependency on <sys/pidfd.h>.
I'll send out a v4 with a fix.
Thanks again for your help.
Best regards,
Wang Lian
