[Bug 1321425] Re: irqbalance spams syslog about affinity_hint subset empty

[Chris J Arges]

Hello Kent, or anyone else affected,

Accepted irqbalance into trusty-proposed. The package will build now and
be available at
https://launchpad.net/ubuntu/+source/irqbalance/1.0.6-2ubuntu0.14.04.3
in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

Bug description:
  [Environment]

  /var/log/syslog has repeating
  May 20 14:39:28 txsllabc7k001 /usr/sbin/irqbalance: irq 121 affinity_hint subset empty
  May 20 14:39:28 txsllabc7k001 /usr/sbin/irqbalance: irq 123 affinity_hint subset empty
  May 20 14:39:28 txsllabc7k001 /usr/sbin/irqbalance: irq 125 affinity_hint [Repeat]

  ProblemType: Bug
  DistroRelease: Ubuntu 14.04
  Package: irqbalance 1.0.6-2
  ProcVersionSignature: Ubuntu 3.13.0-24.47-generic 3.13.9
  Uname: Linux 3.13.0-24-generic x86_64
  ApportVersion: 2.14.1-0ubuntu3.1
  Architecture: amd64
  Date: Tue May 20 14:19:32 2014
  ExecutablePath: /usr/sbin/irqbalance
  ProcEnviron:
   TERM=linux
   PATH=(custom, no user)
  SourcePackage: irqbalance
  UpgradeStatus: No upgrade log present (probably fresh install)

  [Impact]

  Syslog writes a repeated set of affinity_hint entries, affecting logs
  visibility and potentially causing high disk usage.

  [Test]

  - Install irqbalance package.
  - Enable /etc/default/irqbalance
  #Configuration for the irqbalance daemon
  #Should irqbalance be enabled?
  ENABLED="1"
  - Start (service start irqbalance)

  [Regression Potential]

  - None is expected.

  [Other Info]

  The fix is to only warn once for affinity hint subset empty irqs.
