Bug description:
  [SRU justification]
  Before systemd 232, UserTasksMax=infinity is not respected in logind.conf, 
despite the documentation referring to systemd.resource-control(5) for the 
definition of this field. This limits the use of Ubuntu 16.04 and later in 
contexts where a user session should be permitted to allocate large numbers of 
processes.

  [Test case]
  1. Set UserTasksMax=infinity in /etc/systemd/logind.conf.
  2. Create a new login session.
  3. Check the ulimit for user processes with 'ulimit -u'.
  4. Verify that the limit has a numeric value.
  5. Upgrade to systemd from -proposed.
  6. Create a new login session.
  7. Check the ulimit for user processes with 'ulimit -u'.
  8. Verify that the limit is now set to 'unlimited'.

  [Regression potential]
  This is an upstream patch which is part of 232 and later without issues and 
clearly addresses the bug in question.  While the upstream commit includes code 
changes that are not strictly required in order to fix this bug, these are 
mostly cosmetic and should not carry significant additional risk.

[Steve Langasek]

The indicated upstream patch, f50582649f8eee73f59aff95fadd9a963ed4ffea,
does not apply cleanly against systemd 229.  Are there known
prerequisites for this patch?

  This error recreated on the smaller 1U Open Power system with the same 
smaller 1-adapter/1-4U90 drawer/90 HDD. There are 2 cables connected to the 
drawer (one to each ESM) that requires multipath enabled.

  This defect will go to Linux as even after making the below 2 changes
  in systemd resource limit, errors are seen:

  root@yellowbee:/etc/systemd/logind.conf.d# cat htxlogindcustom.conf
  [Login]
  UserTasksMax=infinity
  root@yellowbee:/etc/systemd/logind.conf.d# cat 
../system.conf.d/htxsystemdcustom.conf
  [Manager]
  DefaultTasksAccounting=yes
  DefaultTasksMax=infinity

  root@yellowbee:/etc/systemd/logind.conf.d#

  logind limit for MaxUserTask as well as systemd limit was made infinite.
  Please look defect SW363655 for more details and the suggestion given earlier 
by Linux team.

  errors are still seen. So, would ask Linux team to take a look and see if 
anything else is causing these
  errors.

  == Comment: #3 - Kevin W. Rudd  - 2016-12-19 17:34:27 ==
  It appears that the version of logind on this system does not support the 
value of "infinity", and is reverting to the default of 12288: 

  # cat /sys/fs/cgroup/pids/user.slice/user-0.slice/pids.max
  12288

  As a workaround until this can be resolved, specify an exact
