From 0bdb1db297ab36865a63ee722d35ff0a1f0ae522 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Fri, 19 Feb 2010 14:13:50 -0800 Subject: Btrfs: flush data on snapshot creation Flush any delalloc extents when we create a snapshot, so that recently written file data is always included in the snapshot. A later commit will add the ability to snapshot without the flush, but most people expect flushing.
