✨ ubifs_ro_mode(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for ubifs_ro_mode — yes that's the whole title and yes it's iconic 💅 this one lives in the kernel API docs and it's short, sweet, and honestly kind of dramatic.

🌸 NAME 🌸

ubifs_ro_mode — switch UBIFS to read read-only mode. that's it. that's the vibe. one job, and it does it 🔥

🎀 SYNOPSIS 🎀

void ubifs_ro_mode (struct ubifs_info *c , int err );

returns nothing (void), takes two things, slays quietly 🫶

🦋 ARGUMENTS 🦋

• c — the UBIFS file-system description object. literally the whole file system's little info bundle, main character energy 👑
• err — the error code that is the reason of switching to R/O mode. like, the receipts for why we're panicking 💀
