Subject: [PATCH rdma-next 1/2] kasan: fix compilation warnings due to missing function prototypes
Date: Tue, 12 May 2020 09:37:27 +0300 [thread overview]
Message-ID: <20200512063728.17785-2-leon@kernel.org> (raw)
In-Reply-To: <20200512063728.17785-1-leon@kernel.org>
From: Leon Romanovsky <leonro@mellanox.com>
__asan_report_* function generates the following warnings while compiling
kernel, add them to the internal header to be aligned with other __asan_*
function prototypes.
mm/kasan/generic_report.c:130:6: warning: no previous prototype for '__asan_report_load1_noabort' [-Wmissing-prototypes]
130 | void __asan_report_load##size##_noabort(unsigned long addr) \
| ^~~~~~~~~~~~~~~~~~
mm/kasan/generic_report.c:143:1: note: in expansion of macro 'DEFINE_ASAN_REPORT_LOAD'
143 | DEFINE_ASAN_REPORT_LOAD(1);
| ^~~~~~~~~~~~~~~~~~~~~~~

mm/kasan/generic_report.c:137:6: warning: no previous prototype for '__asan_report_store1_noabort' [-Wmissing-prototypes]
137 | void __asan_report_store##size##_noabort(unsigned long addr) \

mm/kasan/generic_report.c:148:1: note: in expansion of macro 'DEFINE_ASAN_REPORT_STORE'
