The task->flags is a 32-bits flag, in which 31 bits have already been consumed. So it is hardly to introduce other new per process flag. Currently there're still enough spaces in the bit-field section of task_struct, so we can define the memstall state as a single bit in task_struct instead. This patch also removes an out-of-date comment pointed by Matthew.
