[PATCH 060/104] virtiofsd: Add timestamp to the log with FUSE_LOG_DEBUG level |
Date: |

From: Masayoshi Mizuma <address@hidden>
virtiofsd has some threads, so we see a lot of logs with debug option.
It would be useful for debugging if we can see the timestamp.
Add nano second timestamp, which got by get_clock(), to the log with
FUSE_LOG_DEBUG level if the syslog option isn't set.
The log is like as:
]# ./virtiofsd -d -o vhost_user_socket=/tmp/vhostqemu0 -o source=/tmp/share0
-o cache=auto
...
[5365943125463727] [ID: 00000002] fv_queue_thread: Start for queue 0 kick_fd 9
[5365943125568644] [ID: 00000002] fv_queue_thread: Waiting for Queue 0 event
[5365943125573561] [ID: 00000002] fv_queue_thread: Got queue event on Queue 0
