Neil, These are the patches to fix write hole issue. It did everything you requested. - one meta data type format - no super block - format suitable for future extention of caching. - just fix write hole issue, no caching support The recovery doesn't use stripe cache yet, need further tweak of the stripe cache code. I hope it's easy enough. Please let me know how you think.
