From 913d952eb573c3d1f7487e83b5590e13e7cae2bd Mon Sep 17 00:00:00 2001 From: Chris Mason <chris.mason@oracle.com> Date: Tue, 10 Mar 2009 13:17:18 -0400 Subject: [PATCH] Btrfs: Clear space_info full when adding new devices The full flag on the space info structs tells the allocator not to try and allocate more chunks because the devices in the FS are fully allocated. When more devices are added, we need to clear the full flag so the allocator knows it has more space available.
