(2) When executing the command `make cscope`, the `cscope.files` file generated by it includes only filenames with the extensions *.h, *.c, *.S and not includes filenames with *.rs extensions. SOLUTION (1) Modify the regular expression in the `all_compiled_sources()` function so that only files with the extensions *.h, *.c, *.S, and *.rs are accepted. This causes `make COMPILED_SOURCE=1 cscope` command to generate the `cscope.files` file that contains only files with the extensions *.h, *.c, *.S, and *.rs. (2) Modify the functions `find_arch_sources()`, `find_arch_include_sources()`, `find_include_sources()`, and `find_other_sources()` so that they can accept an unlimited number of filename patterns as parameters for the search. Add the `setup_name_pattern()` function to convert these filename pattern parameters into a list of parameters that can be passed to the `find` utility via the new `pattern` variable. This causes `make cscope` command to generate a `cscope.files` file that contains *.rs files along with *.h, *.c, *.S Signed-off-by: Sergei Litvin --- Changes since V3: https://lore.kernel.org/lkml/20260601211850.3378-1-litvindev@gmail.com/ In V3, the functions `find_arch_sources()`, `find_arch_include_sources()`, `find_include_sources()`, and `find_other_sources()` were modified so that they no longer accept the filename pattern as the last argument, but instead retrieve it from the new variable `pattern`. However, at the time, I had overlooked the case where the `find_other_sources` function was called with the `Kconfig*` parameter. And after Sashiko pointed this out to me, I decided to rewrite it in the current version. Changes since V2: https://lore.kernel.org/lkml/20260530085821.19689-1-litvindev@gmail.com/ - The functions find_arch_sources()`, `find_arch_include_sources()`, `find_include_sources()`, and `find_other_sources()` have been modified rather than having their calls duplicated to avoid redundant directory traversals (suggested by Sashiko). – The regular expression in the `all_compiled_sources()` function was improved by adding a lookahead anchor (?=\s) to the first branch (also suggested by Sashiko). Changes between the V1 and V2: https://lore.kernel.org/lkml/20260530085821.19689-1-litvindev@gmail.com/ https://lore.kernel.org/lkml/20260530070631.14955-1-litvindev@gmail.com/ - In Version V1, the `-name` parameters to the `find` calls in the functions `find_arch_sources()`, `find_arch_include_sources()`, `find_include_sources()`, and `find_other_sources()` were replaced by `-regextype posix-extended -regex`. However, as noted by Sashiko, the `-regextype` option is a GNU-specific extension; therefore, in V2, duplicate function calls were introduced instead.
