Two issues comes up while building selftest/landlock:
the first one is as to gettid
net_test.c: In function ‘set_service’: net_test.c:91:45: warning: implicit declaration of function ‘gettid’; did you mean ‘getgid’? [-Wimplicit-function-declaration] "_selftests-landlock-net-tid%d-index%d", gettid(), ^~~~~~ getgid net_test.c:(.text+0x4e0): undefined reference to `gettid'
the second is compiler error gcc -Wall -O2 -isystem fs_test.c -lcap -o /home/linux/tools/testing/selftests/landlock/fs_test fs_test.c:4575:9: error: initializer element is not constant .mnt = mnt_tmp, ^~~~~~~
What is the version of GCC (and headers) and on which system (and version) are you building these tests?
gcc 7.3 / glibc-2.28/ kernel 4.19/ OpenEulor20.03
this patch is to fix them

Sorry for inconvenient, I'll resend it v2 after checkpatch.pl shows no error.

Please follow the same approach: https://git.kernel.org/stable/c/87129ef13603ae46c82bcd09eed948acf0506dbb
