From 9f0ba5bd91d42706ba78f97ec638c6a821db1c5e Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Tue, 18 Nov 2008 10:31:22 -0500 Subject: [PATCH] Btrfs: unplug all devices in the unplug call back For larger multi-device filesystems, there was logic to limit the number of devices unplugged to just the page that was sent to our sync_page function. But, the code wasn't always unplugging the right device. Since this was just an optimization, disable it for now.
