gen_pool_first_fit(9)

💖 gen_pool_first_fit(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ we're literally about to find the first available region of memory that matches the size requirement — and ngl, there's no alignment constraint here, so it's giving chill vibes only 🫶

🌸 NAME 🌸

gen_pool_first_fit — find the first available region of memory matching the size requirement (no alignment constraint) 💅

✨ SYNOPSIS ✨

unsigned long gen_pool_first_fit (unsigned long *map , unsigned long
size , unsigned long start , unsigned int nr , void *data , struct
gen_pool *pool , unsigned long start_addr );

🎀 ARGUMENTS 🎀

• map — the address to base the search on 🔍 like, this is where the hunt begins, bestie
• size — the bitmap size in bits 🧮 yes, in bits, don't come for me
• start — the bitnumber to start searching at 🏁 your starting line, your main character moment
• nr — the number of zeroed bits we're looking for 🌈 that's the actual size of the gap we want
• data — additional data — unused 🙈 literally not used, she's just here for the vibes
• pool — pool to find the fit region memory from 👑 the pool in question, the source of the memory
• start_addr — not used in this function 💀 nope, unused, don't @ me
