hmm....ok....kernel said that.... so...
int yfkm2_is_pid_running(pid_t pid) { struct task_struct *q;
q = find_task_by_vpid(pid);
I think this section that makes kernel barf. It wants you to grab rcu_read_lock(), right before you do find_task_by_vpid(). What do you think? :) -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
