Hi,all
I found it just support a small value for -I option.
when I run '#./hugemmap04 -I 3600 -H /var/hugetlbfs',the test returned
immediately.
the -I option details :
-I x Execute test for x seconds
And if you give a much bigger value to -I option such as 3600 or larger, you
will find the -I option disabled,
so I changed the lib/parse_opts.c file, and just modified the stop_time
variable type from 'int' to 'double',
after changed, it can support a very bigger value for -I option.
v2: modified the patch's format
