Subject: resource: constify arg to resource_size() and resource_type()
X-Git-Tag: v2.6.33-rc1~71^2~9
X-Git-Url: http://pileus.org/git/?a=commitdiff_plain;h=f65380c07b64b0e45ad5c7d70ca54a9cde1c00db;p=~andy%2Flinux

resource: constify arg to resource_size() and resource_type()

resource_size() doesn't change the resource it operates on, so the res
parameter can be marked const.  Same for resource_type().
