⭐ ARGUMENTS ⭐

okay so here's the cast of characters, one by one, no skipping, periodt:

  • idmap — the idmap of the relevant mount. the mapping situation, iykyk. 🗺️
  • path — path of dentry to set XATTR at. this is where the xattr goes, bestie.
  • attr_name — xattr name for setxattr. literally the name of the thing.
  • attr_value — xattr value to set. the actual content, the main character of the operation. 👑
  • attr_size — size of xattr value. gotta know how big the vibe is. 📏
  • flags — destination buffer length. yep, that's what the manpage says, we're reporting it faithfully. 🫶
  • get_write — get write access to a mount. grab that write access, slay. ✍️

🔥 RETURN 🔥

0 on success, otherwise error. that's it, that's the whole return situation. zero means we ate and left no crumbs; anything else means something went sideways. 😭

ngl, always check the return value. 0 is your bestie, errors are not. 💀
