OK, I tried to stop it with 'kill -STOP', but it didn't. So I've added some printk() to fs/buffer.c to verify this (see below). It never goes in the 'else' block, and I don't get the 'kupdate() stopped' message. To make sure I tried all signals (1..29) but no luck. So something else must be wrong.
Cheers, Peter.
int kupdate(void * unused) ... for (;;) { interval = bdf_prm.b_un.interval; if (interval) { printk("kupdate() interval %d\n", interval); tsk->state = TASK_INTERRUPTIBLE; schedule_timeout(interval); printk("kupdate() returned from schedule_timeout\n"); } else { tsk->state = TASK_STOPPED; printk("kupdate() stopped\n"); schedule(); /* wait for SIGCONT */ } printk("kupdate() activated...\n"); sync_old_buffers(); } }
