Subject: [PATCH] syscalls: add sys_ni_posix_timers prototype
Date: Wed, 7 Jun 2023 16:28:45 +0200 [thread overview]
Message-ID: <20230607142925.3126422-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
The sys_ni_posix_timers() definition causes a warning when
the declaration is missing, so this needs to be added
along with the normal syscalls, outside of the #ifdef.
kernel/time/posix-stubs.c:26:17: error: no previous prototype for 'sys_ni_posix_timers' [-Werror=missing-prototypes]
Signed-off-by: Arnd Bergmann <arnd@arndb.de>

I missed sending this out in the initial submission of my Wmissing-prototype patches
