💅 mhi_queue_is_full(9)

okay bestie, welcome to the Kernel API Manual, section 9, and the star of today's episode: mhi_queue_is_full. Yes it's a real function name and yes it's iconic. Sit down, hydrate, let's get into it 🫶

✨ NAME ✨

mhi_queue_is_full — literally just: figure out whether you can even queue new elements or if the thing is, uh, full. that's it. that's the whole vibe check 🔥

---

🌸 SYNOPSIS 🌸

bool mhi_queue_is_full (struct mhi_device *mhi_dev , enum
       dma_data_direction dir );

look at her go. returns a bool, takes two args, no drama 💅

---

🎀 ARGUMENTS 🎀

• mhi_dev — the device that's associated with the channels, bestie. this is your main character 🫶
• dir — the DMA direction for the channel. which way is the data flowing, iykyk ✨

okay this is the part where the manpage just goes absolutely feral and lists, like, everything. ngl it's giving "tag yourself" energy. all of these live in the kernel file ./include/linux/mhi.h 💀

🌈 a lil sign-off 🌈

this absolute gem of a page lives under ./include/linux and it's dated October 2026, and the header's still repping mhi_queue_is_full(9) because consistency is key ✨

kiss kiss, go check your queues, and remember: if it's full, it's full, and that's not a you problem 💖🎀🦋
