This is something I don't understand. Why can you not submit patches
that simply do things like "change method for writing image" and
reduce the difference between suspend2 and mainline? It may be more
work, but I think you will find that incremental changes are a lot
easier for people to review and merge.

Right now, it seems like Linus and Andrew have only two choices:

1. Ignore your submission
2. Merge all of suspend2

We have had complete reworks of entire subsystems in the 2.6 series
without problems, simply because the effort was taken to make the
changes incrementally.

reiser4 has been in -mm for quite a while without being merged into
mainline. I don't think you want the same fate for suspend2.

Finally, I just want to say I appreciate all the effort you (and Pavel
and Rafael) are putting into suspend-to-disk. It is critical
functionality for me and I think we can get both a well functioning
and maintainable implementation.

Thanks,
Rahul
