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. | |

23 | # These were previously generated source files. When you are building the kernel | |
24 | # with O=, make sure to remove the stale files in the output tree. Otherwise, | |
25 | # the build system wrongly compiles the stale ones. | |
