    Btrfs: set page->private to the eb · 4f2de97a
    Josef Bacik 提交于
    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,
