On Fedora 22, build fails: integrity/driver/main.c:121:68: error: macro "__DATE__" might prevent reproducible builds [-Werror=date-time] PRINTK_INFO("%s: Built on %s @ %s\n", __func__, __DATE__, __TIME__); That's with: gcc (GCC) 5.1.1 20150618 (Red Hat 5.1.1-4) Reproducible builds are nice to have, and there's not a lot of value in having the build date and time in the log. Let's just drop them. Signed-off-by: Michael S.
