v9fs_vfs_setattr_dotl(9)

📦 version 7.3.1, in nixpkgs unstable

💅 v9fs_vfs_setattr_dotl(9) — like, the kernel API manual, bestie ✨

okay so picture this: it's a 9p situation, you're deep in the kernel, and somebody needs their file metadata changed. That's this function. It's the dotl flavour (iykyk), it lives in section 9 of the kernel API manual, and honestly? she's giving main character energy in fs/9p. 🦋

🎀 NAME 🎀

v9fs_vfs_setattr_dotl — set file metadata. That's it. That's the whole vibe. You want the metadata set? Bestie, you came to the right function. 💖

✨ SYNOPSIS ✨

int v9fs_vfs_setattr_dotl (struct mnt_idmap *idmap , struct dentry
       *dentry , struct iattr *iattr );

Returns an int, takes three args, no cap. Note the spacing — we are keeping it exactly as the original has it, because copying literal code wrong is a crime and I would simply pass away. 😭

🌸 ARGUMENTS 🌸

  • idmap — the idmap of the mount. Like, the whole identity-mapping situation for this particular mount. She's context, she's lore, she matters. 👑
  • dentry — the file whose metadata you're setting. Your target. Your moment. 🎯
  • iattr — the metadata assignment structure. It's literally the list of "here's what we're changing" — the structure that carries the assignment. Lowkey the most important passenger in the car. 🚗

🦋 SEE ALSO 🦋

Kernel file ./fs/9p/vfs_inode_dotl.c — that's where the source lives, go read her, she's iconic. 📖

And the whole friend group, fr fr:

Every single one, spelled exactly right, because we do not truncate the group chat. 💅

ngl bestie, if you're poking at this one you're probably already in the 9p source, so like… hydrate, take a break, and remember: the dotl suffix is not decoration, it's the whole point. 🫶
