ib_device_register_rdmacg(9)

💖 NAME 💖

okay bestie, this is the ib_device_register_rdmacg(9) page from the Kernel API Manual, and it's literally about registering with rdma cgroup ✨

🎀 SYNOPSIS 🎀

void ib_device_register_rdmacg (struct ib_device *device );

🌸 ARGUMENTS 🌸

• device — the device you're registering so it can participate in resource accounting by rdma cgroup 🫶

🦋 DESCRIPTION 🦋

Register with the rdma cgroup. This should be called before exposing the rdma device to user space applications, so you avoid a resource accounting leak 😭💅

no cap, timing matters here — call it before the device goes out into user space, or the accounting leak vibe check is failed 💀
