It's not working yet - I found an issue with logging and writeback of uncached buffers through the AIL (i.e. the superblock). This only works by good fortune right now and requires uncached buffers to carry their block number internally, so I need to rethink and rework the patch. I think that I will make the superblock buffer a cached buffer once again, but keep the current shortcut to look it up. Doing so will enable me to keep the distinction I created between cached and uncached buffers. It will also solve the AIL flush waiting problem we currently also have with it on freeze/unmount. > I have another big batch of buffer error > handling changes for 3.6 I'm working on right now. How much does it change? I'm also trying to get all the read verify callback infrastructure changes done for 3.6, and i suspect these may step on each other. I've just about got those patches done - testing and bug fixing is happening at the moment....
