[libvirt] [PATCH v2 03/10] conf: store disk source as pointer, for easier manipulation

Eric Blake eblake at redhat.com
Thu Jun 5 22:52:30 UTC 2014


As part of the work on backing chains, I'm finding that it would
be easier to directly manipulate chains of pointers (adding a
snapshot merely adjusts pointers to form the correct list) rather
than copy data from one struct to another.  This patch converts
domain disk source to be a pointer.

In this patch, the pointer is ALWAYS allocated (thanks in part to
the previous patch forwarding all disk def allocation through a
common point), and all other changse are just mechanical fallout of
the new type; there should be no functional change.  It is possible
that we may want to leave the pointer NULL for a cdrom with no
medium in a later patch, but as that requires a closer audit of the
source to ensure we don't fault on a null dereference, I didn't do
it here.
