John Baldwin 2851f51eb1 Revert most of revision 1.235 and fix the problem a different way. We ... can't acquire an sx lock in ttyinfo() because ttyinfo() can be called from interrupt handlers (such as atkbd_intr()). Instead, go back to locking the process group while we pick a thread to display information for and hold that lock until after we drop sched_lock to make sure the process doesn't exit out from under us. sched_lock ensures that the specific thread from that process doesn't go away. To protect against the process exiting after we drop the proc lock but before we dereference it to lookup the pid and p_comm in the call to ttyprintf(), we now copy the pid and p_comm to local variables while holding the proc lock. This problem was found by the recently added TD_NO_SLEEPING assertions for interrupt handlers. Tested by: emaste MFC after: 1 week		2005-10-27 16:47:28 +00:00
