I'll update to add that to the ma= trix as well as put fstest back in the default regressions. trans=3Dvirtio,version=3D9p2000.L,cache=3Dnone,access=3Duser should still be the most stable, but this recent set of patches does chan= ge inode (and inode_no) handling and I believe by default they may stick = around even though with nocache they should always be refreshed. -eric
