Adding locking would be easy enough, wouldn't it? But do any platforms really boot a second CPU before switching to real printk? Given that I see all the smpboot stuff in dmesg, I guess real printk happens first. I admit I haven't actually checked.
adding locking also makes things more fragile in terms of getting the last thing out before you go down in flaming death.... until it's a proven problem, this early, get the message out at all is more important than getting it out perfectly, sometimes. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
