Pavel But that's precisely what you're doing. You're advocating making the behaviour inconsistent. If what you're suggesting is done, you won't be able to simply cat the sysfs entry to know whether sys_syncing is going to be done on the next cycle. You'll also have to have knowledge of whether a cycle has been done since the last time the value is set. The end result will be someone getting trapped and caught out because they think '1' in /sys/power/dont_sync (or whatever it's called) means what it says.
