dm_test_dis...action_state(9)

✨ NAME ✨

Okay so bestie, welcome to a page from the Kernel API Manual — yes, that's the manual name, we're fancy now 💅 The page header up top reads dm_test_dis...action_state(9) (it's truncated, that's just how the header do), and the function living here is dm_test_dispatch_next_event_no_action_state.

What does it even do? Literally this: other states return DM_ISM_NUM_EVENTS. That's the whole vibe check — when the dispatch-next-event logic hits a state that isn't one of the special ones, it hands back DM_ISM_NUM_EVENTS. No cap, that's it. 🦋

🌸 SYNOPSIS 🌸

void dm_test_dispatch_next_event_no_action_state (struct kunit *test );

🎀 ARGUMENTS 🎀

• test — the KUnit test context. That's the whole handoff, she's the main character here, everything else just rides along 🫶
