BUF_LOCKINIT(9)

💅 BUF_LOCKINIT

ok so real talk, this is BUF_LOCKINIT(9) from the Kernel Developer's Manual, and honestly? she's giving "tiny but essential." like she doesn't do much, but without her nothing else works. no cap. ✨

🎀 SYNOPSIS

#include <sys/param.h>
#include <sys/systm.h>
#include <sys/uio.h>
#include <sys/bio.h>
#include <sys/buf.h>

void
BUF_LOCKINIT(struct buf *bp);

yeah bestie, all five of those includes. don't skip them, they're part of the fit 💅

✨ DESCRIPTION

The BUF_LOCKINIT() macro initializes a buffer lock. that's it. that's the whole job. and she ate. 🔥

the argument situation is literally just one:

• bp — the buffer whose lock is to be initialized. like, the actual buffer. the one. the main character. 🫶

ngl this is the init step, so think of it as the lock's origin story — it doesn't lock anything yet, it just gets the lock ready to exist. 🦋
