Subject: [PATCH 00/11] lots of fixes for zero allocation length

Here are the fixes for zero-length commands, that ultimately let
all command go through normal processing, even if they have
zero length.

The first patch is for PSCSI, the others are for IBLOCK and friends.
I tried to order them so that the safest come first.  So for 3.6 you
could choose to stop at patch 1, 2, 3 or 6, or not apply anything
at all.

Testcases included in each patch, when relevant.

Paolo
