Subject: [PATCH] shared/sleep-config: exclude zram devices from hibernation
923a60
 candidates
923a60
923a60
On a host with sufficiently large zram but with no actual swap, logind will
923a60
respond to CanHibernate() with yes. With this patch, it will correctly respond
923a60
no, unless there are other swap devices to consider.
