[PATCH] swsusp: add s2ram ioctl to userland interface
Add the SNAPSHOT_S2RAM ioctl to the snapshot device. This ioctl allows a userland application to make the system (previously frozen with the SNAPSHOT_FREE ioctl) enter the S3 state without freezing processes and disabling nonboot CPUs for the second time. This will allow us to implement the suspend-to-disk-and-RAM (STDR) functionality in the userland suspend tools. Signed-off-by: Luca Tettamanti <kronos.it@gmail.com> Signed-off-by: Rafael J.
