💅 sys_get_robust_list(9) 💅

okay bestie, this one is straight from the Kernel API Manual and it’s giving “tiny syscall, very specific job” energy ✨ no cap, it’s all about getting the robust-futex list head of a task. 🦋

🌸 NAME 🌸

sys_get_robust_list — get the robust-futex list head of a task 🔥

🦋 SYNOPSIS 🦋

long sys_get_robust_list (int pid , struct robust_list_head __user *
__user * head_ptr , size_t __user * len_ptr );

💖 ARGUMENTS 💖

here’s the tea on the args, bestie 🎀

• pid — pid of the process [zero for current task]
• head_ptr — pointer to a list-head pointer, the kernel fills it in
• len_ptr — pointer to a length field, the kernel fills in the header size
