This commit adds support for zpool list command to output the list of ZFS pools in JSON format using '-j' option.. Information about available pools is collected in nvlist which is later printed to stdout in JSON format. Existing options for zfs list command work with '-j' flag. man page for zpool list is updated accordingly.

.Ss Example 1 : No Listing Available ZFS Storage Pools
|
|
The following command lists all available pools on the system.
|
|
In this case, the pool
|
|
.Ar zion
|
|
is faulted due to a missing device.
|
|
The results from this command are similar to the following:
|
|
.Bd -literal -compact -offset Ds
|
|
.No # Nm zpool Cm list

.Ss Example 2 : No Displaying expanded space on a device
|
|
The following command displays the detailed information for the pool
|
|
.Ar data .
|
|
This pool is comprised of a single raidz vdev where one of its devices
|
|
increased its capacity by 10 GiB.
|
|
In this example, the pool will not be able to utilize this extra capacity until
|
|
all the devices under the raidz vdev have been expanded.
