Dan got blown up while running zfs-tests (rsend),= and that resulted on me picking one series of updates from OpenZFS concern= ing dbuf and dmu. There are still few XXX notes for myself, but so far both= debug and non-debug builds have been behaving nicely (debug build used to = run zfs-tests). I have seen myself also panic from arc (ASSERT fired while = running zfs-tests on debuilg build — that was before the work mention= ed above). Most likely need to pick some arc bits as well.

The current wip branch is: https://github.com/tsoome/illumos-gate/tree/r= send if you like to test. The problem about those panics is that t= hey seem to be random, or at least not easily repeatable.
