Hi All, Please look at the following code from the article Sleeping in the Kernel
http://www.linuxjournal.com/node/8144/print 1 set_current_state(TASK_INTERRUPTIBLE); 2 spin_lock(&list_lock); 3 if(list_empty(&list_head)) { 4 spin_unlock(&list_lock); 5 schedule(); 6 spin_lock(&list_lock); 7 } 8 set_current_state(TASK_RUNNING); 9 10 /* Rest of the code ... */ 11 spin_unlock(&list_lock); Is there any chance for the process getting scheduled out of the run-queue at Line# 2 (say the scheduler runs because of timer interrupt)?? If so, the process won't be scheduled again. Right? If so, what is the best solution for preventing that? Thanks, Sudheer
