2.6.33 high cpu usage
With the ATI bug I was hitting earlier fixed, only my btrfs partition
continues to show high cpu usage for some operations.
Rsync, git pull, git checkout and svn up are typicall operations which
trigger the high cpu usage.
As an example, this perf report is from using git checkout to change to
a new branch; the change needed to checkout 208 files out of about 1600
total files. du(1) reports

[PATCH 00/12] block/bio, fs: convert put_page() to put_user_page*()
From: John Hubbard <jhubbard at nvidia.com>
Hi,
This is mostly Jerome's work, converting the block/bio and related areas
to call put_user_page*() instead of put_page(). Because I've changed
Jerome's patches, in some cases significantly, I'd like to get his
feedback before we actually leave him listed as the author (he might
want to disown some or all of these).
