💅 tomoyo_update_mount_acl(9) — a Kernel API Manual moment 🎀

okay so bestie, welcome to the Kernel API Manual, we're looking at tomoyo_update_mount_acl(9) today and honestly? it's giving "small function, big responsibilities" ✨

✨ NAME ✨

tomoyo_update_mount_acl — writes the "struct tomoyo_mount_acl" list 🦋

like, that's the whole vibe. it writes that list. no cap.

🌸 SYNOPSIS 🌸

int tomoyo_update_mount_acl (struct tomoyo_acl_param *param );

literally the whole signature, keep it exactly like that (yes, with the space before the closing paren, she's quirky like that 💅)

🎀 ARGUMENTS 🎀

  • param — a pointer to "struct tomoyo_acl_param". that's it. that's the argument. she's a one-argument icon 👑

💖 DESCRIPTION 💖

so the tea is: it returns 0 on success, and a negative value otherwise 😭 like if something goes wrong you get a negative number, that's your sign 🚩

and the caller holds tomoyo_read_lock — not the function, the caller. so if you're the one calling this, the read lock is your problem, bestie, don't come crying to the manpage 🫶

🌈 SEE ALSO 🌈

bestie this list is LONG, like, "she ate and left no crumbs" long. all of these live in the kernel file ./security/tomoyo/file.c 🍓

fr fr just read them all, iykyk 💀 they're a whole friend group and this function is not the main character, she's just a member of the squad.

okay that's the page!! mwah 💋

sign-off time bestie: this lil beauty lives under ./security/tomoyo, dated October 2026, and it's tomoyo_update_mount_acl(9) forever and always 👑🌺 slay ✨
