Subject: arm64: kernel/sys.c - silence initialization warnings.
Date: Fri, 12 Mar 2021 04:55:46 -0500 [thread overview]
Message-ID: <162859.1615542946@turing-police> (raw)
Building arch/arm64/kernel/sys.o with W=1 throws over 300 warnings:
/usr/src/linux-next/arch/arm64/kernel/sys.c:56:40: warning: initialized field overwritten [-Woverride-init]
56 | #define __SYSCALL(nr, sym) [nr] = __arm64_##sym,
| ^~~~~~~~
/usr/src/linux-next/include/uapi/asm-generic/unistd.h:29:37: note: in expansion of macro '__SYSCALL'
29 | #define __SC_COMP(_nr, _sys, _comp) __SYSCALL(_nr, _sys)
| ^~~~~~~~~
/usr/src/linux-next/include/uapi/asm-generic/unistd.h:34:1: note: in expansion of macro '__SC_COMP'
34 | __SC_COMP(__NR_io_setup, sys_io_setup, compat_sys_io_setup)
| ^~~~~~~~~
We know that's pretty much the file's purpose in life, so tell the
build system to not remind us. This makes the 1 other warning a
lot more noticeable.
