sdma_clean(9)

🧚 sdma_clean(9) 🧚

okay so bestie, this is from the Kernel API Manual, and it's giving “tiny cleanup function that's honestly so chill.” No cap, the whole page is short, but every detail is staying. 💖

✨ NAME ✨

sdma_clean — clean up allocated memory. That's the name and the whole mood. 🎀

🌸 SYNOPSIS 🌸

void sdma_clean (struct hfi1_devdata *dd , size_t num_engines );

Bestie, that signature is exactly what goes in the code block — spacing, semicolon, all of it. ✨

🦋 ARGUMENTS 🦋

• dd — a struct hfi1_devdata. That's the device-data bestie in question.
• num_engines — num sdma engines. Literally the sdma engine count, periodt.

💅 DESCRIPTION 💅

This routine can be called regardless of the success of sdma_init. Like, whether sdma_init popped off or flopped, you can still call sdma_clean — that's the entire vibe. 🫶
