yes,
it flushes buffer on \n
Something like fflush() function can also be used to explicitly flush stdout/stderr in user space, not sure if it is in kernel space...

Subject: printk and \n
Hi
printk("device opened\n");
printk("device file opened by %d", current->pid);
Here the second printk output is not displayed.
Without \n printk is not flushing out its buffer. If I give, \n in the second printk it is working.
Is there any reason for that?
