node_activate_pending_pwq(9)

🎀 node_activate_pending_pwq 🎀

okay so this is the node_activate_pending_pwq(9) page from the Kernel API Manual, and bestie, it's short but it's lowkey important — let's get into it 💖

✨ NAME ✨

node_activate_pending_pwq — Activate a pending pwq on a wq_node_nr_active

🌸 SYNOPSIS 🌸

void node_activate_pending_pwq (struct wq_node_nr_active *nna , struct
       worker_pool *caller_pool );

💅 ARGUMENTS 💅

• nna — the wq_node_nr_active to activate a pending pwq for. that's the main character here 👑
• caller_pool — the worker_pool the caller is locking.

🦋 DESCRIPTION 🦋

so it activates a pwq in nna->pending_pwqs, no cap. this is called with caller_pool locked.

heads up bestie: caller_pool may be unlocked and relocked to lock other worker_pools. like, it's allowed to briefly dip out and come back 🔁

okay that's the whole page 🫶 this one comes from ./kernel, dated October 2026, and the manual name is node_activate_pending_pwq(9). bye bestie, go be iconic with those pending pwqs 💅✨
