trace_ignore_this_task(9)

💅 trace_ignore_this_task(9) ✨

okay so welcome to the Kernel API Manual, bestie — this one's a lil function from the tracing corner of the kernel and it's honestly not that deep, so let's get into it 🫶

🌸 NAME 🌸

trace_ignore_this_task — the vibe check that answers "should this task be ignored for tracing?"

✨ SYNOPSIS ✨

bool trace_ignore_this_task (struct trace_pid_list *filtered_pids ,
struct trace_pid_list *filtered_no_pids , struct task_struct *task );

🎀 ARGUMENTS 🎀

• filtered_pids — the list of pids we're checking against, iykyk
• filtered_no_pids — the list of pids that are not to be traced, no cap
• task — the actual task in question, like the one that should be ignored if it's not filtered 👑

🦋 DESCRIPTION 🦋

so the way this works: it checks whether task should be traced or not, based on filtered_pids. literally that's it.

• returns true if the task should NOT be traced 🙈
• returns false if the task should be traced 💖

ok and yes, the true/false is famously a little scrambled-feeling — true means ignore it, false means trace it. don't come for me, that's just what it says 💀
