James H 5333eb0b3b Call exportfs -v once for NFS shares. ... At the moment we call exportfs -v every time we check whether an NFS share is active. This happens every time you run a zfs or zpool command, making them extremely slow when you have a lot of exports. The time taken is approx O(n2) of the number of shares. This commit stores the output from exportfs -v in a temporary file and use this to speed up subsequent accesses. This mechanism is still too slow - if you have tens of thousands of NFS shares it will still be painful running ANY zfs/zpool command.
