An LJ user pointed me to some very interesting work in this area. He wrote the following:
The Featherstitch filesystem uses clever formal systems techniques to derive softupdates ordering requirements and optimise away unnecessary disk operations. They've basically generalized and automated Kirk McKusick's one-off analysis of FFS's ordering requirements. This technology means softupdates is no longer difficult.
I thought I should share it over here.
