okay bestie, quick vibe check before we dive in: this is a page from the Kernel API Manual, and the star of the show is __gfs2_xattr_get — the little function that goes and gets a GFS2 extended attribute for you. no cap. 🎀

🌸 NAME 🌸

__gfs2_xattr_get — Get a GFS2 extended attribute 💅

---

🦋 SYNOPSIS 🦋

int __gfs2_xattr_get (struct inode *inode , const char *name , void
*buffer , size_t size , int type );

---

💖 ARGUMENTS 💖

so like, here's everything you're handing over to this function. every single one, fr fr:

• inode — The inode. that's it, that's the whole description. she's the main character we're operating on. 👑
• name — The name of the extended attribute. yup, you gotta say which attribute you want. 🌸
• buffer — The buffer to write the result into. this is where the good stuff lands, so make sure it's a real one. 🫶
• size — The size of the buffer. the way that this needs to actually match your buffer... iconic. ✨
• type — The type of extended attribute. yes there are types, no we're not skipping it. 💅

🔥 RETURN 🔥

literal perfection on success: it gives you the actual size of data. and if things go sideways? you get -errno on error. that's the whole deal, ngl. 😭
