Subject: selftests/mlock2: add missing #define _GNU_SOURCE
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=60997feb14d5634fc7a9b18ab3c026ba8d3a5839;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

selftests/mlock2: add missing #define _GNU_SOURCE

On glibc 2.3.6:

    mlock2-tests.c: In function 'seek_to_smaps_entry':
    mlock2-tests.c:158: warning: implicit declaration of function 'getline'

According to the manpage of getline(), it needs _GNU_SOURCE before glibc
2.10.
