Description:
The /sys/power/suspend_stats/last_failed_step file contains
the last failed step in the suspend/resume path.
+
+What: /sys/power/sync_on_suspend
+Date: October 2019
+Contact: Jonas Meurer <jonas@freesources.org>
+Description:
+ This file controls whether or not the kernel will sync()
+ filesystems during system suspend (after freezing user space
+ and before suspending devices).
+
+ Writing a "1" to this file enables the sync() and writing a "0"
+ disables it. Reads from the file return the current value.
+ The default is "1" if the build-time "SUSPEND_SKIP_SYNC" config
+ flag is unset, or "0" otherwise.
