Hello Ted, Andreas,
Shilong posted an email here a week ago below. http://lists.openwall.net/linux-ext4/2015/10/30/2 we identified 10 project quota related xfstest and ported them into ext4/xxx. test number are 304, 305, 299, 244, 196, 134, 108, 107, 106, 050 in xfs. We ported 9/10 tests into ext4/xxx ext4/050 ext4/106 ext4/107 ext4/108 ext4/196 ext4/244 ext4/299 ext4/400 ext4/401 please check https://github.com/wangshilong/xfstests An another patch was not valid since quota utility is different. In order to run ported tests, patched quota-tools and Li Xi ported patch of e2fsprogs required. https://github.com/wangshilong/quota-tools/commits/project http://lists.openwall.net/linux-ext4/2015/10/29/2 Thanks Ihara 11/5/15, 11:45 PM , "linux-ext4-ow...@vger.kernel.org (Li Xi の代理)" <linux-ext4-ow...@vger.kernel.org (pkuelel...@gmail.com の代理)> wrote: >On Fri, Sep 25, 2015 at 1:12 AM, Andreas Dilger <adil...@dilger.ca> wrote: >> On Sep 13, 2015, at 2:20 PM, Li Xi <pkuelel...@gmail.com> wrote: >>> >>> The following patches propose an implementation of project quota >>> support for ext4.
