Subject: lglock: make the per_cpu locks static
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=466cab878ef98a0618734a1fa64a02e5fbf90867;p=openwrt%2Fstaging%2Fblogic.git

lglock: make the per_cpu locks static

The per_cpu locks are not used outside the file which contains the
DEFINE_LGLOCK(), so we can make these symbols static.
