While I understand the desire, I believe that
repetitive listings like this don't really
help much.

Having a single entry of:

F:	arch/*/perf/

would serve the same purpose.

Nominally, the difference between the 2 entries
vs the 1 entry is this:

F:	arch/*/perf/*

Only the specific files in any directory that matches
this pattern but not any files in their subdirectories
are maintained.

F:	arch/*/perf/*/*

Only the files in any top level subdirectory of any
directory that matches this pattern are maintained
but not files in any directory of those subdirectories.

F:	arch/*/perf/

Any file or any file in any subdirectory of any
directory that matches this pattern is maintained.
