Hi,
I am not sure if this is a right place (meminfo) to put this statistic in since
it is the accounting from a specific driver. IIUC, this driver is only installed
in a VM, then this accounting will always be zero if this driver is not installed.
Is this possible to put it in a driver-specific sysfs file (maybe it is better)?
Just some thoughts from me.
Yes, it is only used if run under hypervisor but it is under a config
option for that reason.
There are several balloon drivers that will use it, not only one driver
- virtio, VMWare, HyperV, XEN and possibly others. I made one as an
example. Initially i worked on a patches for debugfs but discussion lead
to put it into a centralized place.
