set_info_state(9)

💅 set_info_state(9) — like, the whole glow-up

okay bestie, welcome to the kernel API manual for set_info_state, straight out of the dm-vdo universe ✨ this one's short and sweet but she's important, so pay attention 🫶

✨ NAME ✨

set_info_state — sets the state of a page_info and puts it on the right list, adjusting counters. that's it, that's the whole vibe 💫

🌸 SYNOPSIS 🌸

void set_info_state (struct page_info *info , enum vdo_page_buffer_state
new_state );

🎀 ARGUMENTS 🎀

• info — the page info you're updating. the main character of this operation 💅
• new_state — the new state you're setting it to. the whole point, honestly 🌈

ngl, this is a two-argument function and both arguments are doing exactly what their names say. iconic behaviour, no notes 👑
