💅 cpqhp_resource_sort_and_combine — the Kernel API Manual era 🎀

ok so bestie, you're looking at a page from the Kernel API Manual — yes, that one — and the star of the show is a lil function called cpqhp_resource_sort_and_combine. She's a tidy-up queen and honestly? she ate. ✨

🌸 NAME 🌸

cpqhp_resource_sort_and_combine — sorts the nodes by their base addresses and does the cleanup, no cap 🧹💖

🦋 SYNOPSIS 🦋

int cpqhp_resource_sort_and_combine (struct pci_resource **head );

🎀 ARGUMENTS 🎀

• head — literally the whole list she's gonna sort and clean up. that's it. that's the argument. main character energy only 🫶

💜 DESCRIPTION 💜

okay so here's the vibe: she takes every single node in the list and sorts them all in ascending order by their base addresses. sorted. organized. iconic. 👑

and then, because she's not just pretty — she's useful — she also does garbage collection by combining adjacent nodes. adjacent besties get merged. it's giving found family. 🥹💅

Returns 0 if success. that's the good ending, we love a 0. 🌈
