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
Hi Wang,
Please try to include the context of what you're replying to in your messages, reading the above I have to _just remember_ what Zi said, and I'm old so that's hard now ;)
Please note that mm tests _must_ work without make headers_install being run.
Your test must not rely upon those.
Thanks, Lorenzo
