test_kuid_r...init_ns_uid0(9)

✨ NAME ✨

test_kuid_root_in_ns_init_ns_uid0 — bestie, this is the one that tests kuid_root_in_ns against the init namespace with UID 0 🎀 (it's a Kernel API Manual page, section 9, iykyk)

🌸 SYNOPSIS 🌸

void test_kuid_root_in_ns_init_ns_uid0 (struct kunit *test );

💅 ARGUMENTS 💅

• test — the KUnit test context, aka the little ✨vibe container✨ the test framework hands you so the test can do its thing 🫶

🦋 DESCRIPTION 🦋

Okay so picture this: this test literally verifies that kuid_root_in_ns correctly identifies UID 0 in the init namespace. That's it, that's the whole flex 💖

It's testing the core namespace traversal logic — the main character energy of the whole thing, no cap. And here's the tea ☕: in the init namespace, UID 0 maps to itself, so it should own the namespace. Periodt. 👑
