This patchset fixes TODO:
"If we're already root, we could skip creating the userns."
Change namespace creation for root and non-root
user differently in create_and_enter_ns() function
in this file:
tools/testing/selftests/capabilities/test_execve.c
Test result with root user:
$sudo make TARGETS="capabilities" kselftest
...

timeout set to 45
selftests: capabilities: test_execve
TAP version 13
