Subject: selftests/vm: remove __USE_GNU in hugetlb-madvise.c
Date: Mon, 16 Jan 2023 11:33:07 -0500
__USE_GNU should be an internal macro only used inside glibc. Either
memfd_create() or fallocate() requires _GNU_SOURCE per man page, where
__USE_GNU will further be defined by glibc headers include/features.h:
#ifdef _GNU_SOURCE
# define __USE_GNU 1
#endif
This fixes:
>> hugetlb-madvise.c:20: warning: "__USE_GNU" redefined
20 | #define __USE_GNU
|
In file included from /usr/include/x86_64-linux-gnu/bits/libc-header-start.h:33,
from /usr/include/stdlib.h:26,
from hugetlb-madvise.c:16:
/usr/include/features.h:407: note: this is the location of the previous definition
407 | # define __USE_GNU 1
