Author: hselasky Date: Thu May 26 09:04:14 2016 New Revision: 300721 URL: https://svnweb.freebsd.org/changeset/base/300721 Log: Add support for runtime modifiable module parameters in the LinuxKPI. Linux module parameters have a permissions value. If any write bits are set we are allowed to modify the module parameter runtime. Reflect this when creating the static SYSCTL nodes.
