0820e15a35 [CIFS] Do not zero non-existent iovec in SendReceive response processing.
Could cause memory leak in some readpaths depending on what junk followed it in the stack.

6ab16d2495 [CIFS] Fix umount --force to wake up the pending response queue, not just
the request queue. Also periodically wakeup response_q so threads can
check if stuck requests have timed out. Workaround Windows server illegal smb
length on transact2 findfirst response.

4a77118cd5 CIFS: Allow wsize to exceed CIFSMaxBufSize
This allows cifs_writepages to send data in larger chunks from the page
cache, without requiring larger memory allocations in other cases.

3e84469d01 [CIFS] Add writepages support to shrink memory usage on writes,
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.

b8643e1b52 [PATCH] cifs: Do not use large smb buffers in response path
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

1da177e4c3 Linux-2.6.12-rc2
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!
