node_add_cache(9)

✨ NAME ✨

okay so bestie, this page is node_add_cache(9), straight from the Kernel API Manual (section 9), and it's here to add cache attribute to a memory node. That's the whole assignment: one function, one cache-attribute moment for a memory node. 💅

💫 SYNOPSIS 💫

here's the exact signature, no cap — keep it cute and keep it copied:

void node_add_cache (unsigned int nid , struct node_cache_attrs
       *cache_attrs );

it returns void, so there's no return value to obsess over. ✨

🎀 ARGUMENTS 🎀

two arguments, both iconic:

• nid — the node identifier that has new cache attributes. it's the "which node is getting this" of it all. 🫶
• cache_attrs — the attributes for the cache being added. it's the struct node_cache_attrs * you're handing over, and it's literally the cache info in question. 💖

🌈 SEE ALSO 🌈

if you're going down the rabbit hole (and honestly? you should, iykyk), go peek at these:
