On my local machine, I'm reproducing this with what Fedora calls 3.7.0-0.rc0.git2.4.fc19.x86_64 (note I found an unrelated but very serious bug in this kernel: http://marc.info/?l=linux-kernel&m=134973394826408&w=2 ) In Fedora we apply several patches on top, but none of them appear as if they would affect btrfs or sync/invalidate paths: http://pkgs.fedoraproject.org/cgit/kernel.git/tree/ Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones libguestfs lets you edit virtual machines.
