nfsd: initialize DRC hash table before registering shrinker
In the Linux kernel, the following vulnerability has been resolved: nfsd: initialize DRC hash table before registering shrinker shrinker_register() precedes the INIT_LIST_HEAD loop and the drc_hashsize store. On weakly-ordered architectures (arm64, ppc), a shrinker scan can observe drc_hashsize before the bucket list heads are initialized, causing a NULL deref in the DRC shrinker callback. Move bucket initialization and the drc_hashsize store before shrinker_register() so the hash table is fully initialized before it becomes visible to the shrinker.
