Subject: [PATCH AUTOSEL 4.9 16/19] kernel/elfcore.c: include proper prototypes
Date: Tue, 1 Oct 2019 12:45:02 -0400 [thread overview]
Message-ID: <20191001164505.16708-16-sashal@kernel.org> (raw)
In-Reply-To: <20191001164505.16708-1-sashal@kernel.org>
From: Valdis Kletnieks <valdis.kletnieks@vt.edu>
[ Upstream commit 0f74914071ab7e7b78731ed62bf350e3a344e0a5 ]
When building with W=1, gcc properly complains that there's no prototypes:
CC kernel/elfcore.o
kernel/elfcore.c:7:17: warning: no previous prototype for 'elf_core_extra_phdrs' [-Wmissing-prototypes]
7 | Elf_Half __weak elf_core_extra_phdrs(void)
| ^~~~~~~~~~~~~~~~~~~~
kernel/elfcore.c:12:12: warning: no previous prototype for 'elf_core_write_extra_phdrs' [-Wmissing-prototypes]
12 | int __weak elf_core_write_extra_phdrs(struct coredump_params *cprm, loff_t offset)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
kernel/elfcore.c:17:12: warning: no previous prototype for 'elf_core_write_extra_data' [-Wmissing-prototypes]
17 | int __weak elf_core_write_extra_data(struct coredump_params *cprm)
| ^~~~~~~~~~~~~~~~~~~~~~~~~
kernel/elfcore.c:22:15: warning: no previous prototype for 'elf_core_extra_data_size' [-Wmissing-prototypes]
22 | size_t __weak elf_core_extra_data_size(void)
| ^~~~~~~~~~~~~~~~~~~~~~~~
Provide the include file so gcc is happy, and we don't have potential code drift
