Hi Suraj, All of the patches to fix BZ 206443 are now on the ext4 git tree: https://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git/log/?h=dev I'm currently giving them a full regression test set using xfstests. Could you run your tests to make sure it looks good for you? I'm hoping to issue a pull request to Linus in time for 5.6-rc3 by this weekend. Also, if you can figure out a way to package up the repro as an xfstests test case, that would be really excellent. I think the challenge is that some of them took a *huge* amount of pounding before they repro'ed, correct? I wasn't actually able to trigger the repro using kvm, but I was only using a 2 CPU configuration. Thanks, - Ted
