💅 DESCRIPTION 💅

okay so bestie, welcome to the Kernel API Manual 💖 — this function returns a cookie 🍪 that you can pass to poll_state_synchronize_srcu, which will return true if a full grace period has elapsed in the meantime. no cap.

It is the caller’s responsibility to make sure that grace period actually happens — for example, by invoking call_srcu after return from get_state_synchronize_srcu. that’s the whole vibe, fr fr. 💜
