On weakly-ordered architectures (arm64, ppc),\na shrinker scan can observe drc_hashsize before the bucket list\nheads are initialized, causing a NULL deref in the DRC shrinker\ncallback.\n\nMove bucket initialization and the drc_hashsize store before\nshrinker_register() so the hash table is fully initialized before\nit becomes visible to the shrinker."
