An EXT4 file-system corruption problem was uncovered with Linux 4.0 that turned out to be an MD RAID0 issue with the Linux kernel in the latest stable series. This RAID corruption issue has now been fixed in the latest kernel Git code.

With this MD fixes pull request, the corruption issue should be fully-resolved. Neil Brown noted in the pull request, "one serious RAID0 data corruption - caused by recent bugfix that wasn't reviewed properly."

This fix is present in the latest Linux Git code and will be found in tomorrow's release of Linux 4.1-rc5. This fix should also be back-ported to the relevant stable, currently-supported kernel series too in short order.
