Hi,
Im running 6.2 RH (2.2.14 smp ) on Intel SMP and non SMP machines
with PII and PIII
Ive written a small kernel module which executes the following
operations in the tq_scheduler bottom halves. I suppose they are safe
enough. But if Im wrong please correct me. Here is the pseudocode ( not c)
void task(void) {
if (current == "kswapd" || current == "kupdated"...etc) {
queue task again
exit
}
for(i=0;i<100;i++){
bh = bread();
invoke an rpc call to send the bh->b_data
}
queue task again;
}
This code worked well in non-smp machines but stumbles badly in SMP ones
. Please Guide me ? SMP crash leaves me no clues it simply either freezes
or gives oops which never appeares in /var/log/messages
