🦋 tomoyo_sb_umount(9) — the Kernel API Manual era 🦋

okay so bestie, welcome to the tomoyo_sb_umount page 💅 this is a manpage from the Kernel API Manual, section 9, and it's literally the hook that security_sb_umount() calls. it's short, it's sweet, it's the whole vibe. let's get into it 🫶

✨ NAME ✨

tomoyo_sb_umount — Target for security_sb_umount(). that's it, that's the job 🎀

🌸 SYNOPSIS 🌸

int tomoyo_sb_umount (struct vfsmount *mnt , int flags );

like… she takes a mount and some flags and hands you back an int. icon behavior honestly 👑

🧚 ARGUMENTS 🧚

  • mnt — Pointer to struct vfsmount. it's giving "the thing that's getting unmounted," the main character of this whole function 💖
  • flags — Unmount options. the little extra details that tell the unmount how to behave ✨

💜 DESCRIPTION 💜

Returns 0 on success, negative value otherwise. no cap, that's the entire description 😭 she's not complicated, she's just honest. zero = slay, negative = not slay. 🌈

🎀 SEE ALSO 🎀

and now the friend group 💅 every single one of these is listed in the kernel file ./security/tomoyo/tomoyo.c and they all get a (9) because they're all kernel API girlies:

thirty of them. thirty!! the way that TOMOYO has a hook for everything and isn't afraid to show it 💀 iykyk 🍓

ngl bestie, if you only remember one thing: success gives you 0, anything else gives you a negative value, and mnt is a struct vfsmount *. don't overthink her, she's a simple icon 🧚‍♀️
