Oleg Nesterov 9f83e45eb5 [PATCH] Fix current_io_context() vs set_task_ioprio() race ...

I know nothing about io scheduler, but I suspect set_task_ioprio() is not safe.

current_io_context() initializes "struct io_context", then sets ->io_context.
set_task_ioprio() running on another cpu may see the changes out of order, so
->set_ioprio(ioc) may use io_context which was not initialized properly.
