💅 page_counter_memparse(9)

okay so bestie, welcome to the kernel API manual — this one's living in section 9, and honestly it's giving "small but mighty" ✨

🌸 NAME 🌸

page_counter_memparse — literally memparse() but make it page counter limits 🎀

✨ SYNOPSIS ✨

int page_counter_memparse (const char *buf , const char *max , unsigned
long *nr_pages );

🦋 ARGUMENTS 🦋

• buf — the string you wanna parse, babes. that's the input, that's the vibe 💅
• max — a string that means the maximum possible value, iykyk 👑
• nr_pages — where the result comes back, in number of pages 📄✨

💖 DESCRIPTION 💖

so here's the tea: it returns -EINVAL, or 0 and nr_pages on success. that's it, that's the whole personality 🫶

and the way that nr_pages is limited to PAGE_COUNTER_MAX? iconic. it will not let you exceed that, periodt 🚫🔥

ngl bestie, always check that return value — -EINVAL means the parse did not slay 💀
