cifs: smbd: Return -EINVAL when the number of iovs exceeds SMBDIRECT_MAX_SGE
While it's not friendly to fail user processes that issue more iovs than we support, at least we should return the correct error code so the user process gets a chance to retry with smaller number of iovs. Signed-off-by: Long Li <longli@microsoft.com> Cc: stable@vger.kernel.org Signed-off-by: Steve French <stfrench@microsoft.com>
