If you mean the tag search functionality, yes. See below.

Documentation for this you can find by running "make help" at the root
of the Kernel source tree.

This functionality is documented in Vim itself. To access the relevant
documentation just run

:help tags

There is also the "cscope" program that can give you information about
which functions call and are being called by which other functions. It
has its own man page.
