https://bugzilla.kernel.org/show_bug.cgi?id=200681 Theodore Tso (tytso@xxxxxxx) changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |tytso@xxxxxxx --- Comment #3 from Theodore Tso (tytso@xxxxxxx) --- So it's not reproducing for me using my standard test framework, kvm-xfstests: https://github.com/tytso/xfstests-bld/blob/master/Documentation/kvm-quickstart.md What I did: Edited your reproducer program to use "./xyz" instead of "/mnt/xyz", compiled it, and put the binary in /tmp/kvm-xfstests-tytso/repro. (/tmp/kvm-xfstests-$USER will get mounted using 9p by kvm-xfstests in the guest OS as /vtmp.) % kvm-xfstests shell ... root@kvm-xfstests:~# mount /vtmp root@kvm-xfstests:~# mke2fs -Fq -t ext4 -O inline_data -I 1024 /dev/vdc /dev/vdc contains a ext4 file system last mounted on /vdc on Wed Aug 1 11:09:56 2018 root@kvm-xfstests:~# mount /vdc [ 761.839810] EXT4-fs (vdc): mounted filesystem with ordered data mode. Opts: (null) root@kvm-xfstests:~# cd /vdc root@kvm-xfstests:/vdc# /vtmp/repro res1 = 17968 res2 = 48 first bytes of data are: 01 02 03... If I have time I can try to repro it with your reproducer, but maybe you can try using kvm-xfstests yourself? I think you will find it is a much more convenient system, and if ext4 users, developers, and bug reports all use the same system it saves a lot of time --- otherwise there are many more of *you* than there is of *me* and I don't scale that well unless I ask people to use common tools and procedures. (See https://thunk.org/gce-xfstests for an introduction to kvm-xfstests and gce-xfstests.) -- You are receiving this mail because: You are watching the assignee of the bug.
