task_participate_group_stop(9)

okay bestie, welcome to task_participate_group_stop(9) from the Kernel API Manual ✨ this is the group-stop participation lore, and it’s lowkey iconic 🫶

🌸 NAME 🌸

task_participate_group_stop — participate in a group stop 💅

✨ SYNOPSIS ✨

bool task_participate_group_stop (struct task_struct *task );

🎀 ARGUMENTS 🎀

• task — the task that’s participating in a group stop 🌀

💅 DESCRIPTION 💅

So task has JOBCTL_STOP_PENDING set and is participating in a group stop. The group stop states are cleared and the group stop count is consumed if JOBCTL_STOP_CONSUME was set. If the consumption completes the group stop, the appropriate SIGNAL_* flags are set. Periodt. 💖

🦋 CONTEXT 🦋

⚠️ bestie, this one must be called with task->sighand->siglock held. That’s the required context, no skipping it 💀

💖 RETURN 💖

It returns true if group stop completion should be notified to the parent, and false otherwise. Simple as that, queen 👑.
