okay bestie, buckle up, because we're diving into dm_test_fil...t601_limited(9) from the Kernel API Manual — yes that's the truncated title, that's just how it's saved, don't @ me 🫶

🎀 ARGUMENTS 🎀

• test — the KUnit test context, aka the little backstage pass this test runs with. it's how KUnit knows which test is which. main character energy fr fr. 👑

heads up bestie: the test list above is exactly the roster from the page — same names, same (9) suffixes, same order. don't go renaming them, they're load-bearing. 😭

aaaand that's the whole page, no filler, no fluff, just vibes and one very well-behaved KUnit test. periodt. 🧚

that was dm_test_fil...t601_limited(9) from the Kernel API Manual, sourced out of ./drivers/gpu/drm/amd/display/... (yes, truncated, that's literally how it's written 💀), dated October 2026. ty for coming to my ted talk, ily, go run your tests. 🌈🫶⭐
