Seth Howell 3f9cbe513b blob: add write_zeroes support ... Unmap does not guarantee that erased blocks will return all zeroes. using write_zeroes when unmapping metadata gives the desired behavior for a blob. Only metadata pages will be cleared with write_zeroes in this patch; blob data clusters will still call unmap. This behavior may be made configurable in a later patch (to allow the user to request zeroing of clusters rather than just unmapping).
