Willem de Bruijn says:
====================
zerocopy refinements
1/4 is a small optimization follow-up to the earlier fix to skb_segment:
check skb state once per skb, instead of once per frag.
2/4 makes behavior more consistent between standard and zerocopy send:
set the PSH bit when hitting MAX_SKB_FRAGS. This helps GRO.
3/4 resolves a surprising inconsistency in notification:
because small packets were not stored in frags, they would not set
the copied error code over loopback. This change also optimizes
the path by removing copying and making tso_fragment cheaper.
4/4 follows-up to 3/4 by no longer allocated now unused memory.
this was actually already in RFC patches, but dropped as I pared
down the patch set during revisions.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
