Subject: Inline foreach macro for internal usage
X-Git-Tag: v1~103
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cf91579b8df997db6af369417d4e439238fb9589;p=thirdparty%2Fkmod.git

Inline foreach macro for internal usage

Avoid calling _next() function because it's an exported function and
linker can not optimize it.

Thanks to "Gustavo Sverzut Barbieri <barbieri@profusion.mobi>" for
suggestion.
