lnc_free(9)

👑 lnc_free(9) — Kernel API Manual, but make it make sense 👑

okay so bestie, welcome to the leaf node cache cleanup corner of the Kernel API Manual. This page is short and iconic: one function, one argument, and then a frankly enormous SEE ALSO group chat. 💅

The whole point: remove a leaf node from the leaf node cache. That’s the mission, no extra lore. ✨

🌸 NAME 🌸

lnc_free — remove a leaf node from the leaf node cache. That’s it, that’s the job. 🎀

🎀 SYNOPSIS 🎀

Here’s the signature, exactly as written — do not come for me about the space before the closing paren, it’s canon:

void lnc_free (struct ubifs_zbranch *zbr );

Translation: it returns void, and it takes a pointer to a struct ubifs_zbranch named zbr. 🫶

🦋 ARGUMENTS 🦋

• zbr — the zbranch of the leaf node. That’s the whole argument, bestie. 💖
