 # filechk is used to check if the content of a generated file is updated.
 # Sample usage:
-# define filechk_sample
-#	echo $KERNELRELEASE
-# endef
-# version.h : Makefile
+#
+# filechk_sample = echo $(KERNELRELEASE)
+# version.h: FORCE
 #	$(call filechk,sample)
+#
 # The rule defined shall write to stdout the content of the new file.
 # The existing file will be compared with the new one.
 # - If no file exist it is created
