[pve-devel] [PATCH 2/4] cpuset: replace 'kind' with an 'effective' boolean

[w.bumiller at proxmox.com]

From: Wolfgang Bumiller <w.bumiller at proxmox.com>

All of our users of this function currently either pass
'effective_cpus' or nothing (undef), and in cgroupv2 the
effective-cpuset file uses a different naming scheme.

Since this is only a distinction between "intended" and
"effective", use this as a boolean instead, for easier
future cgroupv2 support.
