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.
