ice_free_sched_node(9)

💖 ice_free_sched_node(9) — Kernel API Manual 💖

okay so bestie, welcome to the Kernel API Manual page for ice_free_sched_node — this is the little cleanup baddie of the Tx scheduler world, and we're gonna read it together, no cap 🫶✨

🌸 NAME 🌸

ice_free_sched_node — Free a Tx scheduler node from SW DB.

✨ SYNOPSIS ✨

void ice_free_sched_node (struct ice_port_info *pi , struct
       ice_sched_node *node );

🎀 ARGUMENTS 🎀

• pi — port information structure. that's the port-info bestie, holding the context 🌸
• node — pointer to the ice_sched_node struct. literally a pointer to your scheduler node, slay 💅

🦋 DESCRIPTION 🦋

okay so this function frees up a node from the SW DB as well as from HW — both places, bestie, it's giving full cleanup 💖🔥

⚠️ important vibe check: this function needs to be called with port_info->sched_lock held. like, lock held, periodt. don't skip this 🫶
