Path to the logfile where all MARS messages go to.

The logfile must already exist in order to be appended.

Logiles can be rotated by renaming them and creating

|
|
a new empty file in place of the old one.

|
|
|
When switched on (and no logfile exists), the syslog
|
|
|
|
|
may get flooded by printk() messages, leading to performance
|
|
|
|
|
problems if remote syslog forwarding is enabled (and possibly
|
|
|
|
|
in other cases). Thus we recommend to prefer file logging.
|
|
|
|
|
When this option is off, the logfile will be used (if one exists).
