From 580afd76e451deb6772d0507de580fb1df14da6c Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Mon, 8 Dec 2008 19:15:39 -0500 Subject: [PATCH] Btrfs: Fix compressed checksum fsync log copies The fsync logging code makes sure to onl copy the relevant checksum for each extent based on the file extent pointers it finds. But for compressed extents, it needs to copy the checksum for the entire extent.
