v9fs_get_inode_from_fid(9)

💅 v9fs_get_inode_from_fid 💅

okay so bestie, welcome to the Kernel API Manual entry for v9fs_get_inode_from_fid(9) — yes it's a mouthful, yes you're gonna say it eight times today, and yes it's iconic. sit down, grab a matcha 🍓, and let's get into it.

✨ NAME ✨

v9fs_get_inode_from_fid — literally the little helper routine that populates an inode by issuing a attribute request 🎀

like… that's the whole job. it shows up, it asks for attributes, it fills in an inode. main character energy fr fr.

---

🌸 SYNOPSIS 🌸

struct inode * v9fs_get_inode_from_fid (struct v9fs_session_info *v9ses
, struct p9_fid *fid , struct super_block *sb );

ngl the line breaks in that synopsis are giving "texted you at 2am" but it's fine, we copy it exactly 💅

🦋 ARGUMENTS 🦋

okay so three (3) besties walk into this function:

• v9ses — session information. like, the vibes/context of the session. it's the struct v9fs_session_info * and it knows things.
• fid — the fid to issue attribute request for. this is the fid. the one you're asking about. it's the whole point 🫶
• sb — the superblock on which to create inode. that's where the inode gets made. new inode, new me, same superblock ✨

lowkey if you mix these up that's a you problem, they're clearly labeled 😭

🔥 SEE ALSO 🔥

the girlies you should also be reading, no cap:

• Kernel file ./fs/9p/v9fs.h
• enum p9_cache_shortcuts(9)
• enum p9_cache_bits(9)
• struct v9fs_session_info(9)
• v9fs_get_new_inode_from_fid(9)

iykyk — go read them, they're all in the ./fs/9p cinematic universe 👑

okay that's the whole page, you ate that 🍓💖

cute little sign-off bestie: this came out of ./fs/9p, dated October 2026, and it's the v9fs_get_inode_from_fid(9) page — periodt. 🎀✨
