15 | # The source tarball, which is generated by 'git archive', contains everything |
16 | # you committed in the repository. If you have local diff ('git diff HEAD'), | |
17 | # it will go into ${diff_patch}. If untracked files are remaining, the resulting | |
18 | # source package may not be correct. | |
19 | # | |
20 | # Examples: | |
21 | # - You modified a source file to add #include "new-header.h" | |
22 | # but forgot to add new-header.h | |
23 | # - You modified a Makefile to add 'obj-$(CONFIG_FOO) += new-dirver.o' | |
24 | # but you forgot to add new-driver.c | |
25 | # | |
26 | # You need to commit them, or at least stage them by 'git add'. | |
27 | # | |
28 | # This script does not take care of untracked files because doing so would | |
29 | # introduce additional complexity. Instead, print a warning message here if | |
30 | # untracked files are found. | |
31 | # If all untracked files are just garbage, you can ignore this warning. | |
