It doesn't support other architectures. I found the build error on arm and decided to send the fix as it was creating noise on KernelCI: memfd_secret.c: In function 'memfd_secret': memfd_secret.c:42:24: error: '__NR_memfd_secret' undeclared (first use in this function); did you mean 'memfd_secret'? 42 | return syscall(__NR_memfd_secret, flags); | ^~~~~~~~~~~~~~~~~ | memfd_secret Hence I'm adding condition that memfd_secret should only be compiled on supported architectures. Also check in run_vmtests script if memfd_secret binary is present before executing it.
