The typical use case are an architecture or a subsystem that decide to cover all files with -Werror. Today alpha, mips and sparc uses -Werror in almost all their Makefile- with subdir-ccflag-y it is now simpler to do so as only the top-level directories needs to be covered. Likewise if we decide to cover a full subsystem such as net/ with -Werror this is done by adding a single line to net/Makefile. Signed-off-by: Sam Ravnborg Cc: Ingo Molnar Cc: "H.
