| 5 | # When you move, remove or rename generated files, you probably also update |
| 6 | # .gitignore and cleaning rules in the Makefile. This is the right thing |
| 7 | # to do. However, people usually do 'git pull', 'git bisect', etc. without |
| 8 | # running 'make clean'. Then, the stale generated files are left over, often |
| 9 | # causing build issues. |
| 10 | # |
| 11 | # Also, 'git status' shows such stale build artifacts as untracked files. |
| 12 | # What is worse, some people send a wrong patch to get them back to .gitignore |
| 13 | # without checking the commit history. |

| 15 | # So, when you (re)move generated files, please move the cleaning rules from |
| 16 | # the Makefile to this script. This is run before Kbuild starts building |
| 17 | # anything, so people will not be annoyed by such garbage files. |

| 21 | # then will be really dead and removed from the code base entirely. |
