From: Eryu Guan <eguan@linux.alibaba.com>
ddf19c
ddf19c
Introduce "-o log_level=" command line option to specify current log
ddf19c
level (priority), valid values are "debug info warn err", e.g.
ddf19c
ddf19c
    ./virtiofsd -o log_level=debug ...
ddf19c
ddf19c
So only log priority higher than "debug" will be printed to
ddf19c
stderr/syslog. And the default level is info.
ddf19c
ddf19c
The "-o debug"/"-d" options are kept, and imply debug log level.
