6585 sha512, skein, and edonr have an unenforced dependency on extensible dataset

Testing shows that the panic can be prevented by explicitly setting extensible dataset as a dependency for the sha512, edonr, and skein feature flags. Alternatively, the new checksums code could possibly be changed to obviate the need for the dependency.

5882 Temporary pool names

These situations cause SPA namespace collisions when the standard name rpool is used in both cases. The solution is either to give each guest pool a name unique to the host, which is not always desireable, or boot a VM environment containing an ISO image to install it, which is cumbersome. As a side note, this commit includes the removal of `zpool import -r`, which previously did nothing. patch [Magnifier] (14.3 KB) Richard Yao, 2015-04-30 04:33 PM Reviewed by: Matt Ahrens Reviewed by: Igor Kozhukhov Reviewed by: John Kennedy Approved by: Dan McDonald Author: Andriy Gapon
