fscache_resize_cookie(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, so this is a page straight out of the Kernel API Manual and it's about fscache_resize_cookie — literally the glow-up button for the size of a cache object 🎀 ngl, short page, but every word eats.

💅 NAME 💅

fscache_resize_cookie — Request that a cache object be resized

Like, you're formally asking the cache object to change its size. Polite request energy. 🦋

🌸 SYNOPSIS 🌸

void fscache_resize_cookie (struct fscache_cookie *cookie , loff_t
new_size );

Look at that signature, so clean, so iconic. Returns void — it gives nothing back, and honestly? Relatable. 💀

🧚 ARGUMENTS 🧚

  • cookie — The cookie representing the cache object. Yes it's literally called a cookie, no we're not baking, it's the handle for your cache object 🍓
  • new_size — The new size of the object (may be NULL). That's an loff_t, and yes the docs fr say it may be NULL, so that's exactly what we're telling you 🙈

👑 DESCRIPTION 👑

Request that the size of an object be changed. That's it, that's the whole vibe — you're officially asking the cache to resize this object. ✨
