Subject: [merged] checkpatch-warn-on-uses-of-__constant_foo-functions.patch removed from -mm tree To: joe@xxxxxxxxxxx,apw@xxxxxxxxxxxxx,sw@xxxxxxxxxxxxxxxxxx,mm-commits@xxxxxxxxxxxxxxx From: akpm@xxxxxxxxxxxxxxxxxxxx Date: Fri, 04 Apr 2014 12:33:58 -0700 The patch titled Subject: checkpatch: warn on uses of __constant_<foo> functions has been removed from the -mm tree. Its filename was checkpatch-warn-on-uses-of-__constant_foo-functions.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Joe Perches <joe@xxxxxxxxxxx> Subject: checkpatch: warn on uses of __constant_<foo> functions Emit a warning when using any of these __constant_<foo> forms: __constant_cpu_to_be[x] __constant_cpu_to_le[x] __constant_be[x]_to_cpu __constant_le[x]_to_cpu __constant_htons __constant_ntohs Using any of these outside of include/uapi/ isn't preferred as using the function without __constant_ is identical when the argument is a constant.
