Hi All, I have picked up the old ext3/jbd patches a while ago and was trying to figure out how difficult would it be to port them to ext4/jbd2. The gain from these patches to anyone using software RAID should be clear, see: http://lwn.net/Articles/363490/ What is not clear to me at this point is what are the performance implications, if any, of withholding "declared" data writeback until journal commit. I also did not get to estimating the effort involved in the porting to ext4/jbd2. The absence of ext3/jbd "dirty data" buffers list is going to be one of the issues to deal with. Does anyone out there have interest in pushing this forward?
