# source package may not be correct.

|
|
# Examples:
|
|
# - You modified a source file to add #include "new-header.h"
|
|
# but forgot to add new-header.h
|
|
# - You modified a Makefile to add 'obj-$(CONFIG_FOO) += new-dirver.o'
|
|
# but you forgot to add new-driver.c
|
|
#
|
|
# You need to commit them, or at least stage them by 'git add'.

#
|
|
# This script does not take care of untracked files because doing so would
|
|
# introduce additional complexity. Instead, print a warning message here if
|
|
# untracked files are found.
|
|
# If all untracked files are just garbage, you can ignore this warning.
