Btrfs: balance delayed inode updates
While trying to reproduce a delayed ref problem I noticed the box kept falling over using all 80gb of my ram with btrfs_inode's and btrfs_delayed_node's. Turns out this is because we only throttle delayed inode updates in btrfs_dirty_inode, which doesn't actually get called that often, especially when all you are doing is creating a bunch of files. So balance delayed inode updates everytime we create a new inode. With this patch we no longer use up all of our ram with delayed inode updates. Thanks, Signed-off-by: Josef Bacik <jbacik@fb.com>
