We have have made the necessary changes in our module code to expose zevents through both devd and the zpool events ioctl. Now the tunables can be exposed and zpool events tests can be enabled on both platforms. A few minor tweaks to the tests were needed to accommodate the way wc formats output on FreeBSD. zed remains to be ported. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Ryan Moeller <ryan@iXsystems.com> Closes #10008
