I tried to find out what is the current comparation between TOI and µswsusp. Unfortunately I could not find any recent information about the state of hibernation in Linux and how TOI compares to µswsusp (the most recent information I found is from 2009 in talk of merge between Nigel, Machek and Wysocki).
The features matrix seems to be partially out-of-date as µswsusp supports "Multithreaded I/O" since 1.0. Does anyone know some more up-to-date comparison?
