#     
#     Pull kselftest update from Shuah Khan:
#      "This consists of a cleanup patch to undo changes to global .gitignore
#       that added selftests/lkdtm objects and add them to a local
#       selftests/lkdtm/.gitignore.
#     
#       Summary of Linus's comments on local vs. global gitignore scope:
#     
#        - Keep local gitignore patterns in local files.
#     
#        - Put only global gitignore patterns in the top-level gitignore file.
#     
#       Local scope keeps things much better separated. It also incidentally
#       means that if a directory gets renamed, the gitignore file continues
#       to work unless in the case of renaming the actual files themselves
#       that are named in the gitignore"
