[Qemu-devel] [PATCH for-3.0 4/4] tests: torture release-ram in postcopy test

[Peter Xu <peterx@redhat.com>]

The release-ram capability will run some extra code for postcopy to
release used ram right away, let's just turn that on for the postcopy
unix test always to torture that code path too to make sure release-ram
feature won't break again.  The recovery test needs to turn that off
since release-ram cannot coop with that.
