Hi Drew,

We're not accepting anymore drivers for the Kilo release. This was from
a discussion that started back in September and mentioned on the mailing list
a couple of times [1][2], multiple Cinder meetings [3][4], and the last design
summit. The one driver we have from Oracle is a ZFS NFS [5] driver that was
registered before the deadline.

If you could verify with your team if they plan to fix the existing Solaris
ISCSI driver [5], or can we remove it?
