✨ vfs_parse_monolithic_sep(9) ✨

okay so bestie, welcome to the kernel API manual 💅 this one's called vfs_parse_monolithic_sep, and it's basically the "parse my mount string but make it custom-separator" girlie 🎀

---

🌸 NAME 🌸

vfs_parse_monolithic_sep — parse key[=val][,key[=val]]* mount data 💫

---

🦋 SYNOPSIS 🦋

int vfs_parse_monolithic_sep (struct fs_context *fc , void *data , char
*(*sep)(char **) );

---

💖 ARGUMENTS 💖

• fc — the superblock configuration you're filling in 🫶 like, this is the thing getting all the good stuff
• data — the data to parse, literally the blob in question
• sep — callback for separating the next option 🎀 (yes, you get to bring your own separator, main character energy)

---

⭐ DESCRIPTION ⭐

So what it does: it parses a blob of data that's in key[=val][,key[=val]]* form, using a custom option separator callback. Periodt 💅

Returns 0 on success, or the error returned by the ->parse_option fs_context operation on failure 😭 no cap, that's the whole deal.

🚨 heads up bestie: failure means you get that error back — the one from the ->parse_option fs_context operation. Don't go inventing your own, iykyk.
