VFS_UNBUSY(9)

💅 VFS_UNBUSY(9) — Kernel Developer's Manual 💅

okay so bestie, gather round, because we're talking about vfs_unbusy from the Kernel Developer's Manual — yes that one, the section 9 girlies know 🫶

✨ NAME ✨

vfs_unbusy — unbusy a mount point 🌸

✨ SYNOPSIS ✨

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

void
vfs_unbusy(struct mount *mp);

like... two includes and one function, we love a low-effort slay 💅

✨ DESCRIPTION ✨

okay so the vfs_unbusy() function un-busies a mount point by decrementing the reference count of a mount point. and the way that reference count got bumped in the first place?? typically by calling vfs_busy(9) before you get here 🎀 so like, this is the lil "okay we're done here, thank u next" of the pair. periodt.

Its arguments are:

• mp — the mount point to unbusy. that's it. that's the whole job. iconic. 💜

ngl if you never called vfs_busy(9) first, you're out here decrementing a count that you never incremented and the vibe check will NOT pass, so like... pair them up bestie 🙈
