Btrfs: set page->private to the eb We spend a lot of time looking up extent buffers from pages when we could just store the pointer to the eb the page is associated with in page->private. This patch does just that, and it makes things a little simpler and reduces a bit of CPU overhead involved with doing metadata IO. Thanks, Signed-off-by: Josef Bacik <josef@redhat.com>
