Merge branch 'Convert-skb_frag_t-to-bio_vec'
Matthew Wilcox says: ==================== Convert skb_frag_t to bio_vec The skb_frag_t and bio_vec are fundamentally the same (page, offset, length) tuple. This patch series unifies the two, leaving the skb_frag_t typedef in place. This has the immediate advantage that we already have iov_iter support for bvecs and don't need to add support for iterating skbuffs. It enables a long-term plan to use bvecs more broadly within the kernel and should make network-storage drivers able to do less work converting between skbuffs and biovecs. It will consume more memory on 32-bit kernels. If that proves problematic, we can look at ways of addressing it. v3: Rebase on latest Linus with net-next merged. - Reorder the uncontroversial 'Use skb accessors' patches first so you can apply just those two if you want to hold off on the full conversion. - Convert all the users of 'struct skb_frag_struct' to skb_frag_t. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
