Bug Description

== SRU Justification ==
The bug reporter was trying to turn on the RAID journal. One of the steps
is to set the device readonly. This did not work as planned, or indeed at
all. After the first --readonly, all requests for the device report
"No such device or address" until a reboot, though /proc/mdstat says the
device is still there.

This bug is fixed by mainline commit 065e519e71b2c1f41936cce75b46b5ab34adb588,
which is in mainline as of 4.12-rc1. The commit was also cc'd to stable, but
upstream 4.10 is EOL, so that is the reason for the SRU request.

== Fix ==
commit 065e519e71b2c1f41936cce75b46b5ab34adb588
Author: NeilBrown <email address hidden>
Date: Thu Apr 6 11:16:33 2017 +0800

    md: MD_CLOSING needs to be cleared after called md_set_readonly or do_md_stop

== Regression Potential ==
This commit was also cc'd to stable and accepted, so additional upstream review
was performed.

== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.

Please backport upstream fix.

I built a Zesty(4.10 based) test kernel with a pick of commit 065e519e71b2c1f4. The test kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1706243/

Can you test this kernel and see if it resolves this bug?

Thanks in advance!

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-zesty' to 'verification-done-zesty'. If the problem still exists, change the tag 'verification-needed-zesty' to 'verification-failed-zesty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Confirmed with 4.10.0-38-generic from zesty-proposed.

Will this be hitting the 4.11.0 branch as well? I'm actually using the generic-hwe-16.04-edge package on xenial.
