Chris Metcalf f51c0eaee3 procfs: treat parked tasks as sleeping for task state ... Allowing watchdog threads to be parked means that we now have the opportunity of actually seeing persistent parked threads in the output of /proc/<pid>/stat and /proc/<pid>/status. The existing code reported such threads as "Running", which is kind-of true if you think of the case where we park them as part of taking cpus offline. But if we allow parking them indefinitely, "Running" is pretty misleading, so we report them as "Sleeping" instead. We could simply report them with a new string, "Parked", but it feels like it's a bit risky for userspace to see unexpected new values; the output is already documented in Documentation/filesystems/proc.txt, and it seems like a mistake to change that lightly. The scheduler does report parked tasks with a "P" in debugging output from sched_show_task() or dump_cpu_task(), but that's a different API. Similarly, the trace_ctxwake_* routines report a "P" for parked tasks, but again, different API. This change seemed slightly cleaner than updating the task_state_array to have additional rows. TASK_DEAD should be subsumed by the exit_state bits; TASK_WAKEKILL is just a modifier; and TASK_WAKING can very reasonably be reported as "Running" (as it is now). Only TASK_PARKED shows up with unreasonable output here.
