What is /dev/zfs?

Thu Jun 29 14:56:37 UTC 2017

Hi, folks

any pointer to an explanation would be nice,
there seems to be no zfs(4) manpage ...

Reason for asking: I have a piece of software
that uses 14,000 ioctl() calls on that device during
one execution and I'm asking myself what it tries
to do.

Thanks!
Patrick
