Andrew,

This v6 rebases on to linux-next tag next-20210701, and adds a new third
patch to use ATTRIBUTE_GROUPS. This goes run time tested with the LTP
zram02 script. As per Minchan's request, sending this through you.

  zram: fix crashes with cpu hotplug multistate
  zram: fix deadlock with sysfs attribute usage and module removal
  zram: use ATTRIBUTE_GROUPS
