That's the first line of encode_lookup:

static int encode_lookup(struct xdr_stream *xdr, const struct qstr *name)
{
int len = name->len;
__be32 *p;

RESERVE_SPACE(8 + len);

So len is either very large, or it's just garbage. Do you know if
fsstress is trying to do something with a particularly long filename
here?

Hi,

The fsstress creates random file names up to 1024 characters long.

Thanks & regards,
