It means that at runtime block device can be exported or unexported.

Toshi explains:
"No, the default values need to be set to the fallback types,
i.e. minimal supported mode. For WC and WT, UC is the fallback type.
When PAT is disabled, pat_init() does update the tables below to
enable WT per the default BIOS setup. However, when PAT is enabled,
but CPU has PAT -errata, WT falls back to UC per the default values."

The CQM task events are not safe to be called from within interrupt
context because they require performing an IPI to read the counter value
on all sockets. And performing IPIs from within IRQ context is a
"no-no".
Make do with the last read counter value currently event in
event->count when we're invoked in this context.

libnvdimm: fix namespace seed creation
A new BLK namespace "seed" device is created whenever the current seed
is successfully probed. However, if that namespace is assigned to a BTT
it may never directly experience a successful probe as it is a
subordinate device to a BTT configuration.
The effect of the current code is that no new namespaces can be
instantiated, after the seed namespace, to consume available BLK DPA
capacity. Fix this by treating a successful BTT probe event as a
successful probe event for the backing namespace.

Then host driver will know there's a valid card detect function.
