💅 nilfs_get_blocksize(9) — Kernel API Manual 💅

okay bestie, we're in the Kernel API Manual and this page is literally nilfs_get_blocksize(9). no cap, it's about getting the block size from raw superblock data. 🦋

🌸 NAME 🌸

nilfs_get_blocksize — get block size from raw superblock data

✨ SYNOPSIS ✨

int nilfs_get_blocksize (struct super_block *sb , struct
       nilfs_super_block *sbp , int *blocksize );

🎀 ARGUMENTS 🎀

• sb — super block instance, the main character here 💖
• sbp — superblock raw data buffer, aka the raw tea 🍓
• blocksize — place to store block size, the lil output spot ✨

🦋 DESCRIPTION 🦋

okay so nilfs_get_blocksize calculates the block size from the block size exponent information written in sbp and stores it in blocksize. the way that happens is exactly that — no extra lore, iykyk. 💅

and if it's too large, it aborts with an error message. periodt. no quiet fail, no "maybe it's fine", bestie, it's a whole abort. 😭
