I didn't get a chance to test the patch. I'm running into unrelated
issues.

Title:
  Encrypted swap won't load on 20.04 with zfs root

Status in zfs-linux package in Ubuntu:
  Confirmed

Bug description:
  root@eu1:/var/log# lsb_release -a
  No LSB modules are available.
  Distributor ID:       Ubuntu
  Description:  Ubuntu 20.04 LTS
  Release:      20.04
  Codename:     focal

  root@eu1:/var/log# apt-cache policy cryptsetup
  cryptsetup:
    Installed: (none)
    Candidate: 2:2.2.2-3ubuntu2
    Version table:
       2:2.2.2-3ubuntu2 500
          500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages

  OTHER BACKGROUND INFO:
  ======================

  1. machine has 2 drives. each drive is partitioned into 2 partitions,
  zfs and swap

  
  2. Ubuntu 20.04 installed on ZFS root using debootstrap 
(debootstrap_1.0.118ubuntu1_all)

  
  3. The ZFS root pool is a 2 partition mirror (the first partition of each 
disk)

  
  4. /etc/crypttab is set up as follows:

  swap      
/dev/disk/by-id/nvme-SAMSUNG_MZVLB1T0HALR-00000_S3W6NX0M802914-part2    
/dev/urandom   swap,cipher=aes-xts-plain64,size=256
  swap      
/dev/disk/by-id/nvme-SAMSUNG_MZVLB1T0HALR-00000_S3W6NX0M802933-part2    
/dev/urandom   swap,cipher=aes-xts-plain64,size=256


  
  WHAT I EXPECTED
  ===============

  I expected machine would reboot and have encrypted swap that used two
  devices under /dev/mapper


  WHAT HAPPENED INSTEAD
  =====================

  
  On reboot, swap setup fails with the following messages in /var/log/syslog:

  Apr 28 17:13:01 eu1 kernel: [    5.360793] systemd[1]: cryptsetup.target:

  Also, /dev/mapper does not contain any swap devices:

  root@eu1:/var/log# ls -l /dev/mapper
  total 0
  crw------- 1 root root 10, 236 Apr 28 17:13 control
  root@eu1:/var/log#

  
  And top shows no swap:

  MiB Swap:      0.0 total,      0.0 free,      0.0 used.  63153.6 avail
  Mem
