From: Sage Weil Date: Fri, 19 Feb 2010 22:13:50 +0000 (-0800) Subject: Btrfs: flush data on snapshot creation X-Git-Tag: v2.6.34-rc4~3^2~35 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0bdb1db297ab36865a63ee722d35ff0a1f0ae522;p=platform%2Fupstream%2Fkernel-adaptation-pc.git 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.
