ir_resize_table(9)

💅 ir_resize_table(9) — like, the Kernel API Manual page, but make it make sense

okay bestie, welcome to the Kernel API Manual entry for ir_resize_table(9) — yes that's the actual title, no I'm not being extra, it's literally what it says at the top of the page. grab a strawberry drink 🍓 and let's get into it.

✨ NAME ✨

ir_resize_table — resizes a scancode table if necessary

like... it resizes the table if necessary, okay? it's not out here resizing for fun. it checks first. consent is key 💅

---

🦋 SYNOPSIS 🦋

int ir_resize_table (struct rc_dev *dev , struct rc_map *rc_map , gfp_t
gfp_flags );

that's the whole signature, character for character, don't @ me about the spacing, that's just how the page is written 📄✨

---

🎀 ARGUMENTS 🎀

• dev — the rc_dev device. the whole device vibe, the main character of this operation 👑
• rc_map — the rc_map to resize. this is the table we're about to glow up 🌸
• gfp_flags — gfp flags to use when allocating memory. the memory-allocation settings, hand them over and let it cook 🔥

---

💖 DESCRIPTION 💖

so here's the tea ☕ — this routine will shrink the rc_map if it has lots of unused entries, and grow it if it's full.

that's it. that's the whole thing. it's giving ✨adaptive✨. not me being obsessed with a function that just does the sensible thing 😭

lowkey important: it shrinks when there's a bunch of unused entries and grows when the table is full — those are the two conditions, straight from the page, no cap 🫶

---

🔥 RETURN 🔥

zero on success, or a negative error code 😭

so like, 0 = slay, we ate. negative = it did not eat. check your error code bestie, it's literally telling you something 💀
