From: Pablo Neira Ayuso Date: Sat, 8 Sep 2012 02:53:54 +0000 (+0000) Subject: netlink: hide struct module parameter in netlink_kernel_create X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9f00d97;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git netlink: hide struct module parameter in netlink_kernel_create This patch defines netlink_kernel_create as a wrapper function of __netlink_kernel_create to hide the struct module *me parameter (which seems to be THIS_MODULE in all existing netlink subsystems).
