I'm responsible for the release locking changes. But, I don't think that the problems are a result of those changes. There have been some other patches that might have caused the problem. Take a look at this thread:
http://marc.theaimsgroup.com/?l=linux-kernel&m=100745930928683&w=2
Jens Axboe posted a patch. I asked him: > So, what was the actual problem? bio_alloc() not waiting on the reserved pool for free entries, even though __GFP_WAIT was set. No need for __GFP_IO in that case too.
Udo, did you apply the patch that Jens sent?
