bfq_entity_of(9)

💖 NAME — bfq_entity_of(9) 💖

okay bestie, welcome to the bfq_entity_of(9) page from the Kernel API Manual ✨ this is a tiny lil helper with main character energy:

bfq_entity_of — get an entity from a node. no cap, that's literally the whole gig 💅

✨ SYNOPSIS ✨

struct bfq_entity * bfq_entity_of (struct rb_node *node );

🎀 ARGUMENTS 🎀

• node — the node field of the entity. that's the lil piece you're feeding in 🫶

🦋 DESCRIPTION 🦋

So here's the tea: this function converts a node pointer to the relative entity 💖 it's a shortcut, not a universal converter.

⚠️ it is used only to simplify the logic of some functions, and not as the generic conversion mechanism. why? because — for example — in the tree walking functions, the check for a NULL value would be redundant. so yeah, it's a convenience thing, not the glow-up every node gets 😌
