gfs2_setattr(9)

📦 version 7.3.1, in nixpkgs unstable

💅 gfs2_setattr(9) — like, the Kernel API Manual page, bestie ✨

okay so real talk, this is a page straight out of the Kernel API Manual and it's all about gfs2_setattr. it's short, it's sweet, and it's giving "small function, big job" energy tbh 🎀

✨ NAME ✨

gfs2_setattr — change attributes on an inode 🦋

like, the attributes? changing them. on an inode. that's the whole vibe.

🌸 SYNOPSIS 🌸

int gfs2_setattr (struct mnt_idmap *idmap , struct dentry *dentry ,
       struct iattr *attr );

it returns an int, it takes three things, and yes bestie you do have to pass all three 💅

🎀 ARGUMENTS 🎀

  • idmap — the idmap of the mount that the inode was found from 🫶 like, whose mapping are we living in rn
  • dentry — the dentry that's changing 👑 this is the main character, the thing getting a glow-up
  • attr — the structure that's describing the change 📝 it literally holds the whole "what are we doing here" of it all

💖 DESCRIPTION 💖

okay so picture this: the VFS layer rolls up and it wants to change one or more of an inode's attributes. and gfs2_setattr? it's the one who actually writes that change out to disk. no cap, that's the job. ✨

the VFS asks, gfs2 answers, the disk gets the update. periodt. 🔥

⭐ RETURN ⭐

errno 💀 yeah that's it, that's the whole return section. it returns an errno. iconic honestly.
