Have you tried doing a parallel build with make -j$(nproc) or
something like that? It fails for me:
test_ns_current_pidtgid_newns.c:6:10: fatal error:
test_ns_current_pidtgid.skel.h: No such file or directory
#include "test_ns_current_pidtgid.skel.h"
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The problem seems to be that you haven't recorded dependency on the
skeleton file for this new test_ns_current_pidtgid_newns.
But rather than fixing it, let's just fold
test_ns_current_pidtgid_newns into test_progs as well? Then all such
issues will be handled automatically and this test will be executed
regularly.
