irdma_dealloc_ucontext(9)

🎀 NAME 🎀

ok so bestie, welcome to irdma_dealloc_ucontext(9) — that's the page, that's the vibe, and it lives in the Kernel API Manual 🦋. Short version: this function deallocates the user context data structure. It's the cleanup girlie. The one who shows up after the party and takes the trash out. No cap.

✨ SYNOPSIS ✨

void irdma_dealloc_ucontext (struct ib_ucontext *context );

that's it. that's the whole signature. returns void, takes one pointer, zero drama 💅

🌸 ARGUMENTS 🌸

• context — the user context that was created during alloc. yes, that one. the one from irdma_alloc_ucontext. you made it, now you're un-making it. it's giving full circle 🔁
