Unhappy find_get_pid returns null inside jprobe function


In a kernel module I have use jprobe to capture parameters of an open system call, when I pass a single process(in the userspace) id to kernel function find_get_pid(current_pid) returns the actual struct pid but when the process is in a user defined pid namespace find_get_pid(current_pid) returns null inside a jprobe function, but in a different kernel function user defined pid namespace find_get_pid(current_pid) returns pointer to struct pid , any idea why this becomes null inside jprobe function ?
