Title: Illumos #1948 (expandsize property) and #2703 (zfs send progress)

#2703 seems to work very well (zfs send progress reporting)
I need information about #1948 (zpool_reopen) if this can be utilized in Linux in vdev_disk.c (TODO part)
And also the expandsize is currently reporting 16E on my system.

Here is the illumos implementation:
