To circumvent that, we are using the functions: $(sort $(dir $(wildcard $(srcdir)/*/)))) Fixes: fcc8487d477a ("uapi: export all headers under uapi directories") Signed-off-by: Richard Genoud Signed-off-by: Masahiro Yamada --- diff --git a/scripts/Makefile.headersinst b/scripts/Makefile.headersinst index ce753a408c56..c583a1e1bd3c 100644 --- a/scripts/Makefile.headersinst +++ b/scripts/Makefile.headersinst @@ -14,7 +14,15 @@ __headers: include scripts/Kbuild.include srcdir := $(srctree)/$(obj) -subdirs := $(patsubst $(srcdir)/%/.,%,$(wildcard $(srcdir)/*/.)) + +# When make is run under a fakechroot environment, the function +# $(wildcard $(srcdir)/*/.) doesn't only return directories, but also regular +# files.
