Hi all:

This series tries to reduce the code duplication of zerocopy of tun and macvtap

- Move common helpers iov_pages() and zerocopy_sg_from_iovec() to net/core
- Use exist helpers instead of open coding the new one

With this seires, we can do further optimizations on top.

Please review.

Jason Wang (6):
net: move iov_pages() to net/core/iovec.c
net: move zerocopy_sg_from_iovec() to net/core/datagram.c
net: use skb_fill_page_desc() in zerocopy_sg_from_iovec()
net: remove the useless comment in zerocopy_sg_from_iovec()
net: use release_pages() in zerocopy_sg_from_iovec()
net: use skb_copy_datagram_from_iovec() in zerocopy_sg_from_iovec()
