This allows cifs_writepages to send data in larger chunks from the page
cache, without requiring larger memory allocations in other cases.

eliminate the double copy, and improve cifs write performance and
help the server by upping the typical write size from 4K to 16K
(or even larger if wsize set explicitly) for servers which support this.

unless response is larger than 256 bytes. This cuts more than 1/3 of
the large memory allocations that cifs does and should be a huge help to
memory pressure under stress.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
