iput(9)

💖 NAME 💖

okay so this is the iput(9) page from the Kernel API Manual, and it's literally about one thing: putting an inode 💅

iput — put an inode.

✨ SYNOPSIS ✨

the signature is giving "simple but do not underestimate her":

void iput (struct inode *inode );

🎀 ARGUMENTS 🎀

• inode — the inode to put, periodt.

💅 DESCRIPTION 💅

Puts an inode, dropping its usage count. If the inode use count hits zero, the inode is then freed and may also be destroyed 💀

Consequently, iput can sleep 😴 — yes, for real, that's the documented consequence.
