Subject: [PATCH 0/2] statx: Fix DAX attribute collision and handling

There are two issues with the statx DAX attribute in the kernel today:

1) Its value clashes with STATX_ATTR_MOUNT_ROOT as dhowells previously reported
2) It is not set in the statx attributes_mask as reported by xifeng

This short series changes the STATX_ATTR_DAX value, and moves the reporting
from the vfs into the dax-capable filesystems so that they can set the
statx atrributes_mask appropriately.
