I'm wondering whether it's worth expanding the SELinux policy if we will have no fstatfs(2) callers in QEMU. Are you planning to drop the XFS code?
Chris Wedgwood said that on XFS you want to do discard even if the file is preallocated, while this is not true on other filesystems. So I guess the detection code should stay.
In generaly you do not want to discard on a preallocated file, especially not the low-granularity discard you'd get for example from a Win7 box.
