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.
14#
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.
18#
19# This script is not intended to grow endlessly. Rather, it is a temporary scrap
20# yard. Stale files stay in this file for a while (for some release cycles?),
21# then will be really dead and removed from the code base entirely.

27# the build system wrongly compiles the stale ones.
