test_resume mode is to verify if the snapshot data written to swap device can be successfully restored to memory. It is useful to ease the debugging process on hibernation, since this mode can not only bypass the BIOSes/bootloader, but also the system re-initialization. To avoid the risk to break the filesystm on persistent storage, this patch resumes the image with tasks frozen. For example: echo test_resume > /sys/power/disk echo disk > /sys/power/state Suggested-by: Rafael J. Wysocki <redacted> Signed-off-by: Chen Yu <yu.c.chen@intel.com>
