💅 dm_test_panel_power_savings_store_sets_disable(9)

okay so this is from the Kernel API Manual, section 9, and bestie it is such a niche little icon. we're in dm_test_pane...sets_disable(9) territory — buckle up 🎀

---

✨ NAME ✨

dm_test_panel_power_savings_store_sets_disable — Test zero maps to disable 💖

that's literally it. that's the whole job. zero goes in, disable comes out, the vibes are immaculate.

---

🌸 SYNOPSIS 🌸

void dm_test_panel_power_savings_store_sets_disable (struct kunit *test );

returns nothing (void, she's giving "no notes"), takes exactly one thing, and that thing is a test context. slay. 💅

---

🦋 ARGUMENTS 🦋

• test — The KUnit test context. this is the little envelope of state the test framework hands you, and yeah you're gonna need it. it's the KUnit test context. that's the whole description. periodt. ✨

and that's the whole page bestie, no filler, no missing entries, we ate and left zero crumbs 🍓

ngl this one's tiny but the friend group is huge — 69 SEE ALSO gremlins and every single one of them got named. that's the standard now, fr fr.
