Pete Zaitcev reports that with his touchpad, if he lifts the finger

This happens because we don't store coordinates unless we detect a
touch so sometimes we have stale coordinates in queue (from where
the finger left the pad) and averaging makes cursor to jump across
the screen. The solution is to always store the latest coordinates.

[PATCH] knfsd: stop NFSD writes from being broken into lots of little writes to filesystem
When NFSD receives a write request, the data is typically in a number of
1448 byte segments and writev is used to collect them together.
Unfortunately, generic_file_buffered_write passes these to the filesystem
one at a time, so an e.g. 32K over-write becomes a series of partial-page
writes to each page, causing the filesystem to have to pre-read those pages
- wasted effort.
generic_file_buffered_write handles one segment of the vector at a time as
it has to pre-fault in each segment to avoid deadlocks. When writing from
kernel-space (and nfsd does) this is not an issue, so
generic_file_buffered_write does not need to break and iovec from nfsd into
little pieces.
This patch avoids the splitting when get_fs is KERNEL_DS as it is
from NFSd.
