📦 version 7.3.1, in nixpkgs unstable

💖 gfs2_open_common(9) 💖

okay so bestie, welcome to the Kernel API Manual — this one's from the gfs2 girlies, and it's literally the shared helper that both open and atomic_open use. no cap, it's giving "two paths, one function" energy ✨

✨ NAME ✨

gfs2_open_common — the common bit shared by open and atomic_open 🫶

🎀 SYNOPSIS 🎀

int gfs2_open_common (struct inode *inode , struct file *file );

🌸 ARGUMENTS 🌸

  • inode — the inode that's being opened, main character of the whole operation 💅
  • file — the file that's being opened, its plus-one 🎀

🦋 DESCRIPTION 🦋

okay so this is the important part, listen up 👑

This maybe gets called under a glock or not, depending on how it's been called. iykyk.

But — and this is the real tea — for regular files we must always be called under a glock. always. no exceptions, fr fr. 🚨

For other file types, it genuinely does not matter whether we hold the glock or not. do with that what you will 💀

⭐ RETURN ⭐

an error code, or 0 for success. slay 🌈
