lowkey reminder: this page lives in ./drivers/block/rnbd and it's dated October 2026, and the header/footer both call it struct rnbd...ess_info_rsp(9) — the terminal just truncates her name for the aesthetic 💀 she's still struct rnbd_msg_sess_info_rsp at heart.

aaand that's the whole page bestie, slay, go read the kernel source, mwah 💜🎀🌈
