The ''Size'' column indicates the size in bytes of a module (not memory used).<ref>{{cite web|title=Kernel Module Utilities|url=http://www.centos.org/docs/5/html/5.1/Deployment_Guide/s1-kernel-module-utils.html|accessdate=31 Jan 2013|archive-url=https://web.archive.org/web/20160911181750/https://www.centos.org/docs/5/html/5.1/Deployment_Guide/s1-kernel-module-utils.html|archive-date=11 September 2016|url-status=dead}}</ref> The ''Used by'' column indicates how many times the module is in use by running programs. To the right of that is a list of other modules which refer to this one, but this list is sometimes incomplete.<ref>{{cite web|author=((user502515))|title=Re: How to get complete dependency list of kernel modules at runtime|url=https://stackoverflow.com/a/4238010/471751|work=Stack Overflow|access-date=3 November 2024}}</ref> If the module controls its own unloading via a can_unload routine then the used-by count shows as -1, irrespective of the actual count.
