@ Show process type in /proc/ccs/.process_status . |

To be able to determine a process's type, I added "(manager)" if the |
|
|
process is a policy manager and "(execute_handler)" if the process is an |
|
|
execute handler. |

@ Show process information in /proc/ccs/.process_status . |
| 1687 |
|
|
| 1688 |
|
To be able to determine a process's type, I added a command "info PID" |
| 1689 |
|
which returns process information of the specified PID in |
| 1690 |
|
"PID manager=\* execute_handler=\* state[0]=\$ state[1]=\$ state[2]=\$" |
| 1691 |

format. |

@ Use rcu_dereference() when walking the list. |
| 1696 |
|
|
| 1697 |
|
I was using "dependency ordering" for appending an element to a list |
| 1698 |
|
without asking the reader to take a lock. But "dependency ordering" |
| 1699 |
|
is not respected by DEC Alpha or by some aggressive value-speculation |
| 1700 |
|
compiler optimizations. |
| 1701 |
|
|
| 1702 |
|
On such environment, use of "dependency ordering" can lead to system |
| 1703 |
|
crash because the reader might read uninitialized value of newly |
| 1704 |
|
appended element. |
| 1705 |
|
|
| 1706 |
|
To prevent the reader from reading uninitialized value of newly appended |
| 1707 |
|
element, I inserted rcu_dereference() when walking the list. |
