Hi Tejun,
I have a question about CLONE_IO.
In copy_io(), we don't share the io_context if "current" does not have task->io_context set. Does that mean if even if I specify CLONE_IO, two threads might not share io context depending on when clone() happened? Or I am reading the code wrong.
Thanks Vivek
