| |
The posix grep utility doesn't support the longer '--file=pattern_file' command line option which was introduced in commit ce697ccee1a8 ("kbuild: remove head-y syntax"). Let's update Makefile to use '-f pattern_file' to fix the compiling error:
grep: Unknown option 'file=.../scripts/head-object-list.txt' (see "grep --help")
Signed-off-by: Will McVicker <willmcvicker@google.com> --- Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
