VFS_MOUNTEDFROM(9)

✨ VFS_MOUNTEDFROM(9) ✨

okay so bestie, welcome to the Kernel Developer's Manual 💅 today we're talking about vfs_mountedfrom(9) — yes it's a section 9 page, yes it's kernel-dev coded, and yes it's gonna be quick but iconic 🎀

🌸 NAME 🌸

vfs_mountedfrom — sets the mounted from name for a mount

🦋 SYNOPSIS 🦋

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

void
vfs_mountedfrom(struct mount *mp, const char *from);

💖 DESCRIPTION 💖

so the vfs_mountedfrom() function sets the mounted from name for a mount. that's it, that's the job, she's a one-task queen 👑

this value is what statfs(2) uses to fill in f_mntfromname. so like, whatever you set here is literally what shows up in that field, no cap 🫶

in most cases, from is the device that contains the file system — very normal, very demure. but in the case of a pseudo file system, it could be a descriptive name instead, like "devfs" or "procfs" ✨ because pseudo file systems don't have a real device, they just have vibes 🧚
