Btrfs: tune btrfs unplug functions for a small number of devices When btrfs unplugs, it tries to find the correct device to unplug via search through the extent_map tree. This avoids unplugging a device that doesn't need it, but is a waste of time for filesystems with a small number of devices. This patch checks the total number of devices before doing the search.
