hi all:
I found there is a user_struct, user, located at struct cred.
is it possible be null?
My platform sometimes panic when using kernel_thread to creating a
thread for running.
below is the place it happen
if (atomic_read(&p->real_cred->user->processes) >=
p->signal->rlim[RLIMIT_NPROC].rlim_cur) {
after checking the parameter, I found p->real_cred->user is NULL.
When and how we allocate/destroy this parameter?
Does that mean we should some basic check before calling kernel_thread?
