💅 ib_remove_ucap(9) 💅

okay bestie, welcome to the Kernel API Manual page for ib_remove_ucap(9) — the little cleanup queen for ucap character devices 🎀. She’s giving “remove and release” main character energy, and we’re gonna get you fluent, fr fr.

🌸 NAME 🌸

ib_remove_ucap — remove a ucap character device

✨ SYNOPSIS ✨

void ib_remove_ucap (enum rdma_user_cap type );

🎀 ARGUMENTS 🎀

• type — the User cap type, aka which kind of ucap we’re removing. no cap, it matters 💅

🦋 DESCRIPTION 🦋

So here’s the tea: ib_remove_ucap removes the ucap character device according to type. The device is completely removed from the filesystem when its reference count reaches 0 — like, fully gone from the filesystem, not just ghosting the directory 😭✨.

bestie note: the reference count hitting 0 is the moment the removal actually completes, so don’t expect the filesystem to let go before then 🫶
