πŸ’… ib_unregister_driver(9) β€” a Kernel API Manual moment

okay so bestie, welcome to ib_unregister_driver(9), straight out of the Kernel API Manual ✨ this one's short but it matters, so grab your lil iced coffee and let's go πŸŽ€


🌸 NAME 🌸

ib_unregister_driver β€” unregister all IB devices for a driver πŸ‘‘ like, every single one of them, no stragglers


✨ SYNOPSIS ✨

void ib_unregister_driver (enum rdma_driver_id driver_id );

that's it. one arg. void return, so nothing comes back β€” she just does the thing and leaves πŸ’…


🫢 ARGUMENTS 🫢

  • driver_id β€” the driver you're unregistering, bestie. that's the one. point at it and say bye πŸ¦‹

πŸ”₯ DESCRIPTION πŸ”₯

okay so this function is literally a fence for device unregistration 🚧 it's giving "wait for everyone to leave the party before you lock up."

it only returns once all devices associated with the driver_id have fully completed their unregistration and have returned from ib_unregister_device*() β€” like, actually returned, not "yeah I'm basically done" πŸ™ˆ no cap, it waits.

if devices are not yet unregistered? it goes ahead and starts unregistering them for you. very main character energy: it doesn't wait around for permission, it just gets it done ⭐

πŸ’€ BUT β€” and this is the important part β€” this does NOT block creation of new devices with the given driver_id. that responsibility belongs to the caller. yep. that's on you, bestie. it's your job, not hers 🫑
