Hi Guangliang, There were a few hiccups getting the ACL support into Linus's tree, but it's in now, and it appears to work. However, I tried out the tuxera posix test suite at http://www.tuxera.com/community/posix-test-suite/ http://tuxera.com/sw/qa/pjd-fstest-20090130-RC.tgz which has a set of acl tests, and several of them fail. I would like to get the tests to all pass and get them added to the night QA so that we won't be chasing down (as many) strange user reports of permission errors down the line. Are you able to take a look?
