Btrfs: use a list for dirty log pages Setting bits in an io tree for the dirty log pages is really expensive, taking somewhere around 7us on my box. So replace this with a basic list, which makes this operation take .2 us per dirty eb. This makes my sync test go from 4.4 mb/s to 5.8 mb/s. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>
