ksmbd_vfs_getxattr(9)

📦 version 7.3.1, in nixpkgs unstable

🦋 NAME 🦋

okay so this is ksmbd_vfs_getxattr(9) — yes bestie, section 9, the Kernel API Manual, we're in the Big Kernel Energy part of the docs 💅 — and it's the vfs helper for smb get extended attributes value. Translation: it's the little function that goes and fetches an extended attribute's value for you. no cap. 🎀

✨ SYNOPSIS ✨

ssize_t ksmbd_vfs_getxattr (struct mnt_idmap *idmap , struct dentry
*dentry , char *xattr_name , char **xattr_buf );

literally the whole signature, don't @ me, copy it exactly like that 🫶

🌸 ARGUMENTS 🌸

here's the tea on every single parameter, none skipped, we don't do that here 🔥

  • idmap — an idmap. yep, that's the whole description. iconic minimalism, honestly. 👑
  • dentry — the dentry of the file you're grabbing xattrs from. it's giving "which file though" energy.
  • xattr_name — the name of the xattr name to query. yes it says "name of xattr name", I'm just the messenger 😭 (it's the name you're querying, bestie).
  • xattr_buf — the destination buffer for the xattr value. like where the value lands. it's a char ** so it's a pointer to your buffer pointer, main character pointer energy ⭐

💀 RETURN 💀

read xattr value length on success 📏 — otherwise, error. that's it, that's the vibe check: got a length? slayed. got an error? welp. 🙈
