Have been running a large set of xfstests against various server types and comparing where we were earlier this year with now - and see big improvements. Here are some examples from cifs.ko to Samba server e.g. - comparing the 6.3 kernel from earlier this year to the current 6.6 kernel. 10 additional tests pass: No longer skipped: generic/051, 068, 390, 491 No longer failed: generic/049, 069, 434, 474, 505, 524 But ... we do have to check carefully, it looks like we do have two intermittent failures (mount/umount busy regressions due to deferred close) that were introduced after 6.3: New failures: 046, 048 Thank you Paulo, Shyam, Bharath and others for helping work through some of these. From my investigations it looks like we should be able to get 20 to 30 additional test groups (from xfstests, the standard filesystem functional test suite) passing with a series of minor fixes and features. Good progress ... -- Thanks, Steve
