trace_pid_list_is_set(9)

💖 NAME 💖

trace_pid_list_is_set — test if the pid is set in the list. Welcome to the Kernel API Manual, bestie 🫶

✨ SYNOPSIS ✨

bool trace_pid_list_is_set (struct trace_pid_list *pid_list , unsigned
int pid );

🎀 ARGUMENTS 🎀

• pid_list — the pid list to test, aka the list you're giving the vibe check to 💅
• pid — the pid to see if set in the list. Literally the pid number you're asking about 👀

🦋 DESCRIPTION 🦋

Okay so this tests if pid is set in the pid_list, periodt. It's usually called from the scheduler when a task is scheduled — its pid gets checked to see if it should be traced or not ✨. It returns true if the pid is in the list, and false otherwise. That's the whole vibe check, iykyk 💜
