smack_fs_con..._parse_param(9)

💅 smack_fs_context_parse_param — Kernel API Manual

okay bestie, welcome to smack_fs_con..._parse_param(9), a page from the Kernel API Manual ✨ (yes the title is literally abbreviated like that, we don't make the rules, the manpage gods do 🎀). It's a tiny page about one little function that handles exactly one mount parameter. Lowkey iconic for how short it is. Let's get into it 🫶

---

🌸 NAME 🌸

smack_fs_context_parse_param — parses a single mount parameter 💅 one (1) parameter, no more, no notes.

---

✨ SYNOPSIS ✨

int smack_fs_context_parse_param (struct fs_context *fc , struct
fs_parameter *param );

like… that's the whole signature, she's neat, she's tidy, she takes two pointers and returns an int 💖

---

🦋 ARGUMENTS 🦋

• fc — the brand-new filesystem context that's being constructed rn. main character energy, she's literally being built as we speak 🏗️
• param — the parameter. just… the parameter. one of them. the one we're parsing 🙈

---

🔥 DESCRIPTION 🔥

okay so here's the whole vibe: it returns 0 on success ✨, or it returns -ENOPARAM to pass the parameter on (like "not mine bestie, hand it to someone else" 👋), or literally anything else if something went wrong 😭💀

that's it. that's the description. she's short but she's honest, no cap 🌈
