I'd want to know what results this program gives with different systems.
Please test and reply (but don't bother if someone already replied with
the same OS+result). I expect it to print:
- SMP kernels: "page size cut" once in a while
- UP (uniprocessor) kernels: Nothing
- The most important thing is that it never prints "broken data"
Linux 2.6.20-16-server (SMP), Core 2 Duo E6600:
Only one reader: No output
Three readers: After a few minutes "Page size cut" printed by one of them
Linux 2.6.18-028stab027 (UP), Athlon 64 3700+:
Never outputs anything.
Regards,
Philipp
