The shortname for a subsystem, that is primarly used when sending patches over E-mail, is not stored anywhere in the source code. Actually one need to dig git log or mailing list archives. There is no standard, and the Maintainer choose how to short name his/her subsystem. MAINTAINERS file is the right place for storing this information. U is the second letter of Subsystem. This will also enable automatic tools like scripts/get_maintainer.pl to provide the correct short name for each filename in the Kernel source tree.
