Subject: [PATCH 017/217] daxctl: emit counts of total and online memblocks
|
|
|
|
Fir daxctl device listings, if in 'system-ram' mode, it is useful to
|
|
know whether the memory associated with the device is online or not.
|
|
Since the memory is comprised of a number of 'memblocks', and it is
|
|
possible (albeit rare) to have a subset of them online, and the rest
|
|
offline, we can't just use a boolean online-or-offline flag for the
|
|
state.
|
|
|
|
Add a couple of counts, one for the total number of memblocks associated
|
|
with the device, and another for the ones that are online.
