DESCRIPTION
The modinfo utility displays information about the loaded modules. The
format of the information is as follows:
Id Loadaddr Size Info Rev Module Name
where Id is the module ID, Loadaddr is the starting text address in
hexadecimal, Size is the size of text, data, and bss in hexadecimal
bytes, Info is module specific information, Rev is the revision of the
loadable modules system, and Module Name is the filename and descrip‐

The module specific information is the block and character major num‐
