💖 nilfs_btree_node_broken(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this one's from the NILFS2 kernel world and it's literally just a vibe check for btree nodes. Nothing more, nothing less. Let's get into it 🫶

🌸 NAME 🌸

nilfs_btree_node_broken — verify consistency of btree node

like, is this node okay or is it giving broken? that's the whole job 💅

🦋 SYNOPSIS 🦋

int nilfs_btree_node_broken (const struct nilfs_btree_node *node ,
       size_t size , struct inode *inode , sector_t blocknr );

🎀 ARGUMENTS 🎀

• node — btree node block to be examined 🔍 like the actual thing we're side-eyeing
• size — node size (in bytes) 📏 the measurement, in bytes, no cap
• inode — host inode of btree 🌳 the inode that hosts this btree
• blocknr — block number 🔢 the block number, periodt

⭐ RETURN ⭐

0 if normal, 1 if the node is broken.

so yeah — 0 means we're slaying, 1 means it's broken and we're like 😭
