dm_test_repl...nt_null_link(9)

Okay bestie, welcome to the dm_test_repl...nt_null_link(9) glow-up — this is the Kernel API Manual entry for a tiny but iconic test 🧚✨

🌸 NAME 🌸

dm_test_replay_set_event_null_link — verify NULL stream link rejection 💅

🧪 SYNOPSIS 🧪

void dm_test_replay_set_event_null_link (struct kunit *test );

🎀 ARGUMENTS 🎀

• test — the KUnit test context, aka the lil’ test-harness bestie 🧪🫶

💖 DESCRIPTION 💖

So the tea is: amdgpu_dm_replay_set_event should return false when the stream has no associated link. That’s the whole plot — this test is here for that NULL-link rejection moment, no cap. 💀✨
