| |
The command "make -j8 C=1 CHECK=scripts/coccicheck" produces lots of "coccicheck failed" error messages.
I do not know the coccinelle internals, but I guess --jobs does not work well if spatch is invoked from Make running in parallel. Disable --jobs in this case.
Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> ---
Changes in v2: - Grep '-j' instead of '--jobserver-auth'. '--jobserver-*' is not a stable option flag. Make 4.2 change '--jobserver-fds' into '--jobserver-auth' - Add -q option to grep
