Hi, I am using 2.4.20 kernel. I have a query. I create two POSIX threads from the same process and one of them calls an IO call and it blocks. Then does the scheduler allow the other thread to run??? I mean do I need to do something special to make the scheduler aware of these threads. Regards, Nilanjan -- Kernelnewbies: Help each other learn about the Linux kernel.
