inode_set_iversion(9)

💅 inode_set_iversion(9) — a Kernel API Manual moment

okay so picture this: you're deep in the kernel API manual (section 9, obviously) and you land on inode_set_iversion(9). bestie. this is the one. let's go 🎀

✨ NAME ✨

inode_set_iversion — sets i_version to a particular value. that's it. that's the whole vibe. 💖

🌸 SYNOPSIS 🌸

void inode_set_iversion (struct inode *inode , u64 val );

like… two args, no return. void. it does the thing and dips. iconic. ✨

🦋 ARGUMENTS 🦋

• inode — the inode you're setting, bestie. that's the target. 🎯
• val — the brand-new i_version value you wanna set it to. the fresh fit. 💅

💜 DESCRIPTION 💜

okay so here's the tea: this function sets the inode's i_version field to val. periodt. 🫶

but like — pay attention — it's specifically for filesystems with a kernel-managed i_version, and it's for initializing a newly-created inode from scratch. brand new inode, zero history, no notes. 🌱

and the way that it does not set the QUERIED flag?? not a bug, it's a feature. we skip it because we know this value has never been queried. literally never been looked at. no cap. so there's nothing to mark. 🙂‍↕️✨

lowkey important context: kernel-managed i_version only. that's the whole qualifier. don't come at this function with anything else. 🚫
