kernfs_put(9)

💅 kernfs_put(9) 💅 — straight from the Kernel API Manual, bestie

okay so we're doing the kernfs_put(9) page, and it's short but iconic. Buckle up 🎀

🌸 NAME 🌸

kernfs_put — put a reference count on a kernfs_node

✨ SYNOPSIS ✨

void kernfs_put (struct kernfs_node *kn );

🎀 ARGUMENTS 🎀

• kn — the target kernfs_node.

🦋 DESCRIPTION 🦋

okay so kernfs_put() literally puts a reference count of kn, and if that count reached zero, it destroys it. That's the whole move, bestie — no extra lore, no secret side quest.

The key vibe check: it destroys kn only if the count reached zero. Periodt. 💅
