[ Upstream commit 5704bc7e8991164b14efb748b5afa0715c25fac3 ]
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.
Fixes: 91b2c0afd00c ("selftests/bpf: Add parallelism to test_progs")
