I opened a PR against our rocksdb repo just so I could comment on the code: https://github.com/ceph/rocksdb/pull/8 I made a bunch of comments. This looks like a great start! My main question is what the purpose of the xattr functions is. I don't see any callers, and I think an omap object for the directory mapping should be sufficient. It looks like there are a bunch of Makefile changes in that commit that probably don't need to be included? sage
