✨ rg_mblk_search(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for rg_mblk_search — she's a kernel function, she's lowkey doing the most, and we're gonna get into it 💅

🎀 NAME 🎀

rg_mblk_search — find a group of multiple free blocks to form a reservation

🌸 SYNOPSIS 🌸

void rg_mblk_search (struct gfs2_rgrpd *rgd , struct gfs2_inode *ip ,
       const struct gfs2_alloc_parms *ap );

✨ ARGUMENTS ✨

• rgd — the resource group descriptor, aka the vibe check on which resource group we're looking at 🫶
• ip — pointer to the inode for which we're reserving blocks, like the main character who needs the space 👑
• ap — the allocation parameters, the little settings bundle dictating how the allocation goes down
