| Series | [v2] fstest: CrashMonkey tests ported to xfstest Inbox x | expand |
Hi all, This is a gentle reminder to review the patch porting the first set of CrashMonkey tests to xfstest. Do let me know if this patch requires any correction, so that I can incorporate them and send out all patches as soon as possible. > Here is the new patch porting the first set of CrashMonkey tests to > xfstests.

Sorry, I've been busy trying to get to the bottom of the data corruption problems exposed by new fsx functionality. I've still a fair way from the bottom, so it might be a while before I get back to this. Cheers, Dave.

As we talked in private mails, hopefully I'll do full review in this week, and it'll be very helpful if you could send a former patch without line-damages so I can apply it and actually run the test more easily. I attached the 'quick review' from our private email so others could see the review comments. Thanks, Eryu On Sun, Nov 18, 2018 at 09:07:42AM -0600, Vijaychidambaram Velayudhan Pillai wrote: > Hi Eryu, > > Could we please get your comments on the updated patch? We’d be happy to change > the patch as required. Sorry for the late review! As it's a relatively big patch and needs more time to do careful review, and recently I don't have much time on review.. Hopefully I'll get it done in next week. But after a very quick glance, overall it looks much better now. But I noticed that the patch still has some un-addressed review comments, for example, there're still some wrapped-lines (perhaps your mail client is misconfigured?) and the indention is still spaces not tab, and it'd be better to create fs with 256MB in size (as I suggested in my previous review comments, because btrfs creates fs in mixed mode if fs size is smaller than 256MB).

And you could just send out the patch with "git send-email" command, so the wrapped-line issue should be fixed. > > > > --- > > > > diff --git a/tests/generic/517 b/tests/generic/517 > > new file mode 100755 > > index 0000000..3e92fbb > > --- /dev/null > > +++ b/tests/generic/517 > > @@ -0,0 +1,183 @@ > > +#! /bin/bash > > +# SPDX-License-Identifier: GPL-2.0 > > +# Copyright (c) 2018 The University of Texas at Austin.

The 'regress' group is still under discussion, and we could do the conversion in a separate patchset when the decision is made. Thanks!

Hi all, I've resent the patch with a detailed commit log, using git send-email, which should solve the line wrap issue. I've also addressed minor nits as pointed out by Eryu. Thanks, Jayashree Mohan
