You seem to be running afoul of the check here:
case Opt_minorversion: if (result.uint_32 > NFS4_MAX_MINOR_VERSION) goto out_of_bounds; ctx->minorversion = result.uint_32; break;
which would seem to indicate that the mount process is supplying minorversion=X as an option. Can you modify your kernel to print param->key and param->string at the top of nfs_fs_context_parse_param()? Adding something like:
pr_notice("NFSOP '%s=%s'\n", param->key, param->string);
will likely suffice unless you're directly driving the new mount API - in which case param->string might be things other than a string, but that's unlikely. It might also be NULL, but printk should handle that.
