Bug Description

SRU Justification:

Impact:
User reports excessive ALUA messages on Ubuntu Trusty, kernel Ubuntu-lts-4.4.0-91.114_14.04.1
Messages appear after a LUN disappears and there are hundreds of them flooding the log...

[263095.795873] sd 3:0:0:129: alua: rtpg retry
[263095.795874] sd 3:0:0:129: [alua] Sense Key : Illegal Request [current]
[263095.795876] sd 3:0:0:129: [alua] Add. Sense: Logical unit not supported

This causes an intense requeing of the ALUA work queue for 60 seconds and it floods the kernel log

Fix:
UBUNTU: scsi: fixe excessive ALUA (LP: #1720228)

BugLink: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1720228

The err value was initialized to 0 to prevent random assignemtn
the fix is a cherry-pick from linus tree a4bd85203190990ad808abbd4a5dc848a950002c

Testcase:
User reports issue when a network iscsi disk gets disconnected.

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-xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed-xenial'.

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!

I have just verified the -proposed kernel, and the correction works as expected.

To be more specific, I did the tests on this release: 4.4.0-117-generic #141~14.04.1-Ubuntu SMP Thu Mar 15 11:45:35 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
