test_progs fails to be compiled in the 32-bit arch, log is as follows:
test_progs.c:1013:52: error: format '%ld' expects argument of type 'long int', but argument 3 has type 'size_t' {aka 'unsigned int'} [-Werror=format=] 1013 | sprintf(buf, "MSG_TEST_LOG (cnt: %ld, last: %d)", | ~~^ | | | long int | %d 1014 | strlen(msg->test_log.log_buf), | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | | | size_t {aka unsigned int}
Fix it.
