Subject: [PATCH] NFSD: copy the whole verifier in nfsd_copy_write_verifier
References: bsc#1012628
Patch-mainline: 6.2.3
Git-commit: 90d2175572470ba7f55da8447c72ddd4942923c4
[ Upstream commit 90d2175572470ba7f55da8447c72ddd4942923c4 ]
Currently, we're only memcpy'ing the first __be32. Ensure we copy into
both words.
Fixes: 91d2e9b56cf5 ("NFSD: Clean up the nfsd_net::nfssvc_boot field")
