🌸 NAME 🌸

security_fs_context_submount — initialises fc->security 💖

✨ SYNOPSIS ✨

int security_fs_context_submount (struct fs_context *fc , struct
super_block *reference );

🎀 ARGUMENTS 🎀

  • fc — the brand-new filesystem context, fresh out the box, main character energy 👑
  • reference — the dentry reference for the submount/remount, aka the vibe it's referencing 💫

🦋 DESCRIPTION 🦋

So what it does is, it fills out the ->security field for a new fs_context. That's it. That's the whole personality. Lowkey iconic for how simple it is ngl 💅

⭐ RETURN ⭐

Returns 0 on success, or a negative error code on failure. No in-between, no "it depends", periodt 💀

Kernel file ./security/security.c, plus literally the entire guest list of the LSM function party — no cap, here's every single one 🎊

ok that's the whole page bestie, go touch some fs_context and hydrate 💧🌸

sign-off era: this little love letter comes from the ./security corner of the tree, dated October 2026, and it's filed under security_fs_...ext_submount(9) — yes the header truncates it, no we don't know why, mwah 💋🧚‍♀️
