Before: LD .../linux/tools/bpf/resolve_btfids/resolve_btfids-in.o LINK resolve_btfids CHK kernel/kheaders_data.tar.xz After: LD .../linux/tools/bpf/resolve_btfids/resolve_btfids-in.o LINK resolve_btfids CHK kernel/kheaders_data.tar.xz The line starting with "LINK" has the filename "resolve_btfids" one space character more to the right than the other lines. It's slightly confusing when scanning the build logs. > > Signed-off-by: Thomas Weißschuh <linux@weissschuh.net> > > --- > > tools/testing/selftests/bpf/Makefile | 2 +- > > 1 file changed, 1 insertion(+), 1 deletion(-) > > > > diff --git a/tools/testing/selftests/bpf/Makefile b/tools/testing/selftests/bpf/Makefile > > index c22c43bbee19..5190c19295d4 100644 > > --- a/tools/testing/selftests/bpf/Makefile > > +++ b/tools/testing/selftests/bpf/Makefile > > @@ -98,7 +98,7 @@ Q = > > msg = > > else > > Q = @ > > -msg = @printf ' %-8s%s %s%s\n' "$(1)" "$(if $(2), [$(2)])" "$(notdir $(3))" "$(if $(4), $(4))"; > > +msg = @printf ' %-7s%s %s%s\n' "$(1)" "$(if $(2), [$(2)])" "$(notdir $(3))" "$(if $(4), $(4))"; > > MAKEFLAGS += --no-print-directory > > submake_extras := feature_display=0 > > endif > >

Thanks! I would be great if you can put the details about (1) what are the command line to reproduce the issue, and (2) what the output differences, to the commit message in all three patches. > > It's slightly confusing when scanning the build logs. > >>> Signed-off-by: Thomas Weißschuh <linux@weissschuh.net> >>> --- >>> tools/testing/selftests/bpf/Makefile | 2 +- >>> 1 file changed, 1 insertion(+), 1 deletion(-) >>> >>> diff --git a/tools/testing/selftests/bpf/Makefile b/tools/testing/selftests/bpf/Makefile >>> index c22c43bbee19..5190c19295d4 100644 >>> --- a/tools/testing/selftests/bpf/Makefile >>> +++ b/tools/testing/selftests/bpf/Makefile >>> @@ -98,7 +98,7 @@ Q = >>> msg = >>> else >>> Q = @ >>> -msg = @printf ' %-8s%s %s%s\n' "$(1)" "$(if $(2), [$(2)])" "$(notdir $(3))" "$(if $(4), $(4))"; >>> +msg = @printf ' %-7s%s %s%s\n' "$(1)" "$(if $(2), [$(2)])" "$(notdir $(3))" "$(if $(4), $(4))"; >>> MAKEFLAGS += --no-print-directory >>> submake_extras := feature_display=0 >>> endif >>>

The common layout for kbuild messages is as follows: - 2 spaces - 7 or more characters for the action - 1 space - name of the file being built/generated The custom message formatting included an additional space in the action part, which leads to misalignments with the rest of kbuild.
