Description

In the Linux kernel, the following vulnerability has been resolved: nfsd: initialise nfsd_info.mutex early. nfsd_info.mutex can be dereferenced by svc_pool_stats_start() immediately after the new netns is created. Currently this can trigger an oops. Move the initialisation earlier before it can possibly be dereferenced.
