VFS_UNMOUNTALL(9)

💅 VFS_UNMOUNTALL — like, the kernel dev manual page, bestie ✨

okay so this is a section 9 page from the Kernel Developer's Manual, and it's about vfs_unmountall — the little function that says bye-bye to every file system at once. it's giving "closing time at the mall" energy 🎀

🌸 NAME 🌸

vfs_unmountall — unmount all the file systems, no cap 🦋

✨ SYNOPSIS ✨

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

void
vfs_unmountall(void);

💖 DESCRIPTION 💖

so the vfs_unmountall function is only run at system shutdown — like, that is its whole moment, its main character arc, its one job 🫶

and what it does is unmount all mounted file systems, going from most recent to oldest. why that order? because it's avoiding having to deal with dependencies, periodt. newest first, oldest last, and nobody has to think about who needs who 💅

heads up bestie: this is a shutdown-only situation. not a "call it whenever" situation. it's literally the last dance 🌈
