Just added 20 more xfststests to the SMB3 Linux client 'buildbot' automated tests (from the surprisingly large set of xfstests that depend on reflink support) to Samba with vfs_btrfs (these tests were added to the cifs-testing group on the buildbot). I suspect that there are about 20 more reflink related existing xfstests that could be added fairly easily, and another ~80 that require additional fallocate features or bugfixes or will only work on local block devices so not appropriate for SMB3 mounts. Continuing to make progress in improving automated testing. Next step is to automate some of the testing of the SMB3.1.1 POSIX extensions to Samba -- Thanks, Steve
