Subject: [PATCHSET 0/3] common/dm*: support external log and rt devices
Date: Mon, 19 Jul 2021 18:09:02 -0700	[thread overview]
Message-ID: <162674334277.2651055.14927938006488444114.stgit@magnolia> (raw)

Hi all,

There are a growing number of fstests that examine what happens to a
filesystem when the block device underneath it goes offline.  Many of
them do this to simulate system crashes, and none of them (outside of
btrfs) can handle filesystems with multiple devices.  XFS is one of
those beasts that does, so enhance the dm-error and dm-flakey helpers to
take the log and rt devices offline when they're testing the data

If you're going to start using this mess, you probably ought to just
pull from my git trees, which are linked below.

This is an extraordinary way to destroy everything.  Enjoy!
Comments and questions are, as always, welcome.
