VREFCNT(9)

💖 VREFCNT 💖 — aka vrefcnt(9), bestie's lil kernel helper

okay so real talk: this is a page from the Kernel Developer's Manual, and it's about one single function that answers one single question — how many people are holding onto this vnode rn? 🫶

✨ NAME ✨

vrefcnt — literally just returns the use count of a vnode. that's it. that's the whole job. and she does it flawlessly 💅

🌸 SYNOPSIS 🌸

first you gotta pull in the headers, no skipping:

#include <sys/param.h>
#include <sys/vnode.h>

and here's the function signature, character for character, don't come for me:

int
vrefcnt(struct vnode *vp);

🦋 DESCRIPTION 🦋

Returns the use count of a vnode. ✨

that's the whole vibe. you hand her a vnode, she tells you how many references are out there living their lives.

and if you wanna know the deep lore of vnode reference counts — like why they matter, what they mean, the whole saga — go read vnode(9), it's got a detailed description waiting for you. she's the main character, this page is just her hype squad 💜
