[PATCH v8] drivers/misc: sysgenid: add system generation id driver

does not guarantee complete snapshot safety to applications using it. A certain workflow needs to be followed at the system level, in order to make the system snapshot-resilient. Please see the "Snapshot Safety Prerequisites" section in the included documentation. Signed-off-by: Adria

[PATCH v7 2/2] drivers/virt: vmgenid: add vm generation id driver

the driver also adds it as device randomness to improve kernel entropy following VM snapshot events. This patch builds on top of Or Idgar 's proposal https://lkml.org/lkml/2018/3/1/498 Signed-off-by: Adrian Catangiu --- Documentation/virt/vmgenid.rst | 36 ++ MAINTAINERS
