💅 cdns3_allocate_trb_pool(9) — the Kernel API Manual, but make it make sense 💅

okay so bestie, we're in the Kernel API Manual today and the main character is cdns3_allocate_trb_pool(9) ✨ it's one of those tiny-but-load-bearing little gremlins from the cdns3 USB gadget world, and honestly? it's giving "small function, big responsibility" 🎀

🌸 NAME 🌸

cdns3_allocate_trb_pool — literally just allocates the TRB's pool for whichever endpoint you selected 🦋 no cap, that's the whole gig.

✨ SYNOPSIS ✨

int cdns3_allocate_trb_pool (struct cdns3_endpoint *priv_ep );

look at her go 😌 one function, one argument, zero drama.

🎀 ARGUMENTS 🎀

  • priv_ep — the endpoint object 💖 that's it, that's the whole vibe. you hand her your endpoint and she takes it from there.

🔥 DESCRIPTION 🔥

so here's the tea ☕ this function will return 0 on success — slay, we love a clean zero — or -ENOMEM on allocation error 😭 which is just the kernel's way of saying "bestie, there's no memory left, I literally cannot".

no in-between, no surprises, just those two outcomes. periodt 💅
