In case there's any hesitation in applying this (Paolo asked if this was just for debugging in v1), being able to pass "-static" is helpful for our environment as our test systems have a funky and minimal configuration (no gcc, and the interpreter is in a weird location). Running selftests either requires building them with -static or creating a symbolic link for /lib64/ld-linux-x86-64.so.2. It's generally easier to just tell people to compile with -static. > Signed-off-by: Anup Patel <anup.patel@wdc.com> > --- Reviewed-and-tested-by: Sean Christopherson <seanjc@google.com>

Currently, I am waiting for some reviews on the PATCH4 (last patch). Regards, Anup

We add EXTRA_CFLAGS to the common CFLAGS of top-level Makefile which will allow users to pass additional compile-time flags such as "-static". Signed-off-by: Anup Patel <anup.patel@wdc.com> --- tools/testing/selftests/kvm/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
