Subject: [PATCH] time: posix-stubs: provide compat itimer supoprt for alpha
Date: Sat, 7 Dec 2019 20:10:26 +0100 [thread overview]
Message-ID: <20191207191043.656328-1-arnd@arndb.de> (raw)
Using compat_sys_getitimer and compat_sys_setitimer on alpha
causes a link failure in the Alpha tinyconfig and other configurations
that turn off CONFIG_POSIX_TIMERS.
Use the same #ifdef check for the stub version as well.
Reported-by: Guenter Roeck <linux@roeck-us.net>
Reported-by: kbuild test robot <lkp@intel.com>
Fixes: 4c22ea2b9120 ("y2038: use compat_{get,set}_itimer on alpha")
