Subject: [PATCH 1/4] module_param: bool params should still work with #include <stdbool.h>
Date: Mon, 09 Feb 2009 18:22:26 +1030 [thread overview]
Message-ID: <20090209075610.3D86CDDDA2@ozlabs.org> (raw)
Code such as "module_param(foo, bool, 0400)" no longer compiles if one
includes stdbool.h: the ISO standard requires that this "#define bool
_Bool".
The fix is simple: define those as well.
