schedule_page_save(9)

🎀 schedule_page_save(9) 🎀

okay bestie, welcome to the Kernel API Manual page for schedule_page_save(9). This one is short and iconic: it adds a page to the outgoing list of pages waiting to be saved. no cap. 💖

✨ NAME ✨

• schedule_page_save — Add a page to the outgoing list of pages waiting to be saved.

🛠️ SYNOPSIS 🛠️

void schedule_page_save (struct page_info *info );

🌸 ARGUMENTS 🌸

• info — The page info to save. that's the whole argument, bestie, and it's giving “just hand over the page info.” 🫶

🦋 DESCRIPTION 🦋

so here's the vibe: this puts a page into the outgoing list of pages waiting to be saved.

and like, once it's in that list, a page may not be used until it has been written out. that's the caveat, and it's important — don't try to use it before then. periodt. 💅
