For each of those modinfos modinfo serializes various info LibKMod has parsed from device files.
After parsing commandline flags modprobe initializes logging, fills in missing parameters, initializes a LibKMod context having it parse its "resources", & runs a chosen subsubcommand.
These subcommands may output various properties of the LibKMod context, output loaded version numbers, output a module's symbols, or hand off to rmmod or insmod.
