reassign_resources_sorted(9)

💅 reassign_resources_sorted(9)

okay so this is a page straight out of the Kernel API Manual, and it's about reassign_resources_sorted — yes bestie, that's the whole name, we're not abbreviating, we're not shortening it, we respect her 🎀

---

✨ NAME ✨

reassign_resources_sorted — satisfy any additional resource requests 🌸

like, the whole job. that's it. she provides. she satisfies. periodt.

---

🦋 SYNOPSIS 🦋

void reassign_resources_sorted (struct list_head *realloc_head , struct
       list_head *head );

returns void, takes two struct list_head * pointers, and the spacing in that signature is exactly how the original has it — don't come for me, I'm keeping it character for character 😭

---

🎀 ARGUMENTS 🎀

• realloc_head — head of the list tracking requests requiring additional resources. it's giving "the wishlist" energy ✨ these are the elements that are like "hey… I need more" 🙈
• head — head of the list tracking requests with allocated resources. this one's the "already got mine" list, lowkey the established icon of the two 👑

---

💖 DESCRIPTION 💖

so here's the vibe: it walks through each element of the realloc_head — every single one, no skipping, main character energy — and tries to procure additional resources for that element, provided the element is in the head list.

that "provided" is doing a lot of work, ngl. the element has to already be in head for the extra resources to happen. no membership, no resourcing. that's the rule, iykyk 🫶

walk the list → check it's in head → try to get it more resources. slay, that's the algorithm 💅
