Need to check the specific symbol "/" in attr_value part as well.
I checked some multipath configuraion files from the sosreport and got
although there are some more specific symbols like "-%", it is enclosed
in double quotes and will be accepted. Furthermore, I also checked the
source code of "device-mapper-multipath" and got if the attr_value in
"multipath.conf" include a "whitespace", it must be enclosed in double
quotation marks. So, we could just add one more specific symbol "/" to
check.
