Hi, this update contains a few fixes (error handling, quota leak, FUA vs nobarrier mount option). There's one one worth mentioning separately - an off-by-one fix that leads to overwriting first byte of an adjacent page with 0, out of bounds of the memory allocated by an ioctl. This is under a privileged part of the ioctl, can be triggerd in some subvolume layouts.
