"kvm-xfstests smoke" runs most of the tests successfully, modulo a few expected failures, but then the kernel locks up after executing "echo 3 > /proc/sys/vm/drop_caches; cat /proc/slabinfo" in the test framework, which happens just before it halts the VM. I suspect there is a bug in my commit (f9f56f19dc) which lets ext4 use the older shrinker API which is used by the 3.10 kernel. It's on my todo list to look at, but I'm in Mountain View this week and my time has been almost toally sucked up by meetings, so I haven't gotten to it yet. So in case you end up doing some testing of the 3.10 backport branch, I thought I should give you a quick heads up.
