[PATCH v6 03/10] Optimize the function of filter_send |
Date: |
Thu, 8 Apr 2021 23:20:49 -0400 |
From: "Rao, Lei" <lei.rao@intel.com>
The iov_size has been calculated in filter_send(). we can directly
return the size.In this way, this is no need to repeat calculations
in filter_redirector_receive_iov();
