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
