00400000-00623000 r-xp 00000000 fd:00 1048990                            /home/vagrant/go-http-demo/main

...
7ffe501e6000-7ffe50207000 rw-p 00000000 00:00 0                          [stack]
7ffe50311000-7ffe50315000 r--p 00000000 00:00 0                          [vvar]
7ffe50315000-7ffe50317000 r-xp 00000000 00:00 0                          [vdso]
ffffffffff600000-ffffffffff601000 --xp 00000000 00:00 0                  [vsyscall]

so no map will be fond as m.Perms != nil && m.Perms.Read && m.Perms.Write && m.Perms.Execute required in findKeyvalMmap.
