ib_device_unregister_rdmacg(9)

💖 NAME 💖

ib_device_unregister_rdmacg — unregister with the rdma cgroup.

Welcome to the ib_device_unregister_rdmacg(9) page, bestie — yes, that is the manual name, and yes, it is a whole mouthful 💅. This is the Kernel API Manual entry for unregistering with the rdma cgroup.

✨ SYNOPSIS ✨

void ib_device_unregister_rdmacg (struct ib_device *device );

🎀 ARGUMENTS 🎀

• device — the device to unregister. That's the whole assignment, no cap 🫶.

🌸 DESCRIPTION 🌸

Okay so: this function unregisters with the rdma cgroup. The important part is when you call it — it should be called after all the resources are deallocated, and after a stage when any other resource allocation by a user application cannot be done for this device. Why? To avoid any leak in accounting. Not me being dramatic, that is literally the point 💅.

🔥 SEE ALSO 🔥

• Kernel file ./drivers/infiniband/core/cgroup.c
• ib_device_register_rdmacg(9)

until next time, bestie 🫶 — this one comes from the Kernel API Manual, sourced at ./drivers/infiniband/core, dated October 2026, and it is still proudly wearing the name ib_device_unregister_rdmacg(9) 💖
