Agree. In retrospect it was my laziness in the dax-device
implementation to expect the block-device to be available.
It looks like fs_dax_get_by_bdev() is an intercept point where a
dax_device could be dynamically created to represent the subset range
indicated by the block-device partition. That would open up more
That seems like a decent short-term plan. But in the long I'd just let
dax call into the partition table parser directly, as we might want to
support partitions without first having to create a block device on top
of the dax device. Same for the badblocks handling story.
