Thanks for the report. This is already dealt with, but to be sure the
issue doesn't fall through the cracks unnoticed, I'm adding it to
regzbot, the Linux kernel regression tracking bot:

#regzbot ^introduced 6e890c5d502
#regzbot title vhost: ps output changed and suspend fails when VMs are
running
#regzbot ignore-activity

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
