Bug description:
== SRU Justification, XENIAL, BIONIC ==
Exercising ZFS with lxd with many mount/umounts can cause lockups and
120 second timeout messages.
== How to reproduce bug ==
In a VM, 2 CPUs, 16GB of memory running Bionic:
sudo apt update
sudo apt install lxd lxd-client lxd-tools zfsutils-linux
sudo lxd init
(and with the default init options)
then run:
lxd-benchmark launch --count 96 --parallel 96
This will reliably show the lockup every time without the fix. With
the fix (detailed below) one cannot reproduce the lockup.
== Fix ==
Upstream ZFS commit
commit ac09630d8b0bf6c92084a30fdaefd03fd0adbdc1
Author: Brian Behlendorf <behlendorf1@xxxxxxxx>
Date: Wed Jul 11 15:49:10 2018 -0700
Fix zpl_mount() deadlock
== Regression Potential ==
This just changes the locking in the mount path of ZFS and will only
affect ZFS mount/unmounts. The regression potential is small as this
touches a very small code path that has been exhaustively exercises
this code under multiple thread/CPU contention and shown not to break.
------------------
ZFS bug report: https://github.com/zfsonlinux/zfs/issues/7691
"I am using LXD containers that are configured to use a ZFS storage backend.
I create many containers using a benchmark tool, which probably stresses the use of ZFS.
In two out of four attempts, I got

[ 726.068979] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
Describe how to reproduce the problem
Start an Ubuntu 18.04 LTS server.
Install LXD if not already installed.
sudo apt update
sudo apt install lxd lxd-client lxd-tools zfsutils-linux
Configure LXD with sudo lxd init. When prompted for the storage
backend, select ZFS and specify an empty disk.
$ sudo lxd init
Would you like to use LXD clustering? (yes/no) [default=no]:
Do you want to configure a new storage pool? (yes/no) [default=yes]:
Name of the new storage pool [default=default]:
Name of the storage backend to use (dir, zfs) [default=zfs]:
Create a new ZFS pool? (yes/no) [default=yes]:
Would you like to use an existing block device? (yes/no) [default=no]: yes
Path to the existing block device: /dev/sdb
Would you like to connect to a MAAS server? (yes/no) [default=no]:
Would you like to create a new local network bridge? (yes/no) [default=yes]: no
Would you like to configure LXD to use an existing bridge or host interface? (yes/no) [default=no]: no
Would you like LXD to be available over the network? (yes/no) [default=no]:
Would you like stale cached images to be updated automatically? (yes/no) [default=yes]
Would you like a YAML "lxd init" preseed to be printed? (yes/no) [default=no]:
Now run the following to launch 48 containers in batches of 12.
lxd-benchmark launch --count 48 --parallel 12
In two out of four attempts, I got the kernel errors.
I also tried
echo 1 >/sys/module/spl/parameters/spl_taskq_kick
but did not manage to continue.
Include any warning/errors/backtraces from the system logs
