free_image_page(9)

🌸 NAME 🌸

okay so bestie, welcome to free_image_page(9) from the Kernel API Manual — the page for the little function that frees a page allocated for a hibernation image. yes, that's the vibe: free_image_page — Free a page allocated for hibernation image. 🫶

✨ SYNOPSIS ✨

void free_image_page (void *addr , int clear_nosave_free );

🎀 ARGUMENTS 🎀

• addr — the address of the page you're freeing, bestie. literally where it lives.
• clear_nosave_free — if this is set, clear the PageNosaveFree bit for the page. that's it, that's the job 💅

🦋 DESCRIPTION 🦋

the page you're freeing should have been allocated by get_image_page — and yes, the page flags set by it are affected. no cap, that's the important bit. 🧚
