tid_flush_pages(9)

💖 NAME — tid_flush_pages(9) from the Kernel API Manual 💖

okay so bestie, this is tid_flush_pages, and its whole vibe is dump out pages into pagesets. literally that's the name line. no cap 💅

✨ SYNOPSIS ✨

u32 tid_flush_pages (struct tid_rdma_pageset *list , u32 *idx , u32 pages , u32 sets );

🎀 ARGUMENTS 🎀

• list — the list of pagesets, aka the lineup 💖
• idx — pointer to the current page index, so it knows where we're at
• pages — number of pages to dump, periodt
• sets — current number of pagesset (that's the page's spelling, bestie 😭)

🌸 DESCRIPTION 🌸

This routine flushes out the pages that have been accumulated. iconic behavior ✨

To insure an even number of sets, the code may add a filler. yes, a filler, because the sets gotta stay even 🎀

This can happen when pages is not a power of 2 or when pages is a power of 2 less than the maximum pages. those are the conditions, fr fr 🫶

🔥 RETURN 🔥

The new number of sets. that's the return value, bestie — the fresh set count 👑
