 * Task state bitmask. NOTE! These bits are also

 * encoded in fs/proc/array.c: get_task_state().

 *

 * We have two separate sets of flags: task->state

 * is about runnability, while task->exit_state are

 * about the task exiting. Confusing, but this way

 * modifying one set can't modify the other one by

 * mistake.
