[PATCH v2 01/10] powerpc/pseries/vas: Use common names in VAS capability structure

Thu Dec 23 11:25:02 AEDT 2021


target/used/avail_creds provides credits usage to user space via
sysfs and the same interface can be used on PowerNV in future.
Remove "lpar" from these names so that applicable on both PowerVM
and PowerNV.
