Comment 2 for bug 1587686

Interestingly this fixes the issue in 4.4.0-23-generic but not 4.4.0-23-lowlatency, and it appears my local builds of master-next on both 4.4.0-24-generic and 4.4.0-24-lowlatency fail still. perhaps something in the 4.4.10 sublevel patches changed something. I've also merged 4.4.11 and 4.4.12 into master-next for my local build to test against those and so far my generic build hasn't failed but on master-next plus 4.4.11 merged it was failing. something is fishy and I'm not sure where, but there's multiple bug reports upstream regarding ztest and some patches in master - but this truncated cache file patch should have been in 0.6.5-release anyways.

Also in case this matters, I've been testing on a 2 node NUMA machine (2x xeon) with ECC memory with no reported memory errors.
