Hi, Thanks for posting. I read the paper and the design looks nice. Then I looked at the patches, but could not find a place to start, nor something I could actually try out. So let me suggest some ways to make this more reviewer/tester friendly: 1) try starting with something very simple yet working and supporting the final layout - no optimizations (one big lock, no per-cpu data, rcu, numa, etc support) - no support for optional features (checksumming, NFS export, etc) - missing mandatory features (e.g. just readdir and getattr support) - try and get it down to <5k lines, preferably 2-3k 2) pointer to sources and instructions for trying it out without special hardware 3) build on this minimal working version by - adding mandatory features - then adding optimizations 4) each patch should leave the tree in a compiling and working state but should be small and easily reviewed 5) leave optional features and unimportant optimizations for a later submission; try to make the patchset as small as you meaningfully can (i.e. it should be fully working and demonstrate the capabilities and performance, but nothing more).
