	Christoph -- I have a question about one part of the patches. In
throttle_vm_writeout() you added a clause that checks for __GFP_FS |
__GFP_IO and if they're not both set it calls blk_congestion_wait()
immediately and then returns, no change for looping. Two questions:

1. This seems like an unrelated bug fix. Should you submit it as a
standalone patch?

This may be a leftover from earlier times when the logic was different in 
throttle vm writeout?
