Re: pm loss development

What do you mean by safe state?

I need to get more details on this but I assume its a state where the
meta data of the file system is committed to the emmc before lights go
off such that when power is reapplied that the damage isn't too big. 

I don't think you can guarantee that the metadata won't be damaged
without notifying the filesystem of the event (and making it react
appropriately).

Journalling filesystem should survive power loss at random time, as
long as block device behaves like a disk (i.e. writes whole sectors).

And that can be guaranteed at driver level...
