Subject: [PATCH 18/56] migration: rename enabled_capabilities to capabilities
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
RH-Author: Peter Xu <peterx@redhat.com>
RH-MergeRequest: 162: migration: Pretty failures for postcopy on unsupported memory types
RH-Bugzilla: 2057267
RH-Acked-by: Leonardo Brás <leobras@redhat.com>
RH-Acked-by: Miroslav Rezanina <mrezanin@redhat.com>
RH-Acked-by: quintela1 <quintela@redhat.com>
RH-Commit: [17/50] 841a27addf273d8f559bc8ebd2c854200e8ca673 (peterx/qemu-kvm)
It is clear from the context what that means, and such a long name
with the extra long names of the capabilities make very difficilut to
stay inside the 80 columns limit.
