ext2_splice_branch(9)

🎀 ext2_splice_branch(9) — Kernel API Manual 🎀

💖 NAME 💖

ext2_splice_branch — splice the allocated branch onto inode. That's the whole name, bestie, and it ate. 💅

✨ SYNOPSIS ✨

void ext2_splice_branch (struct inode *inode , long block , Indirect
       *where , int num , int blks );

🦋 ARGUMENTS 🦋

• inode — owner. Like, the owner. That's the vibe.
• block — (logical) number of block we are adding.
• where — location of missing link.
• num — number of indirect blocks we are adding.
• blks — number of direct blocks we are adding.

🌸 DESCRIPTION 🌸

Okay so this function fills the missing link and does all the housekeeping needed in inode (->i_blocks, etc.). In case of success we end up with the full chain to new block and return 0. No cap, that's literally the whole glow-up. ✨
