When sending multiple requests, rte_mp_request_sync
can succeed sending a few of those requests, but then
fail on a later one and in the end return with rc=-1.
The upper layers - e.g. device hotplug - currently
handles this case as if no messages were sent and no
memory for response buffers was allocated, which is
not true. Fixed by always initializing message buffer
to NULL and calling free everytime rte_mp_request_sync
is used.
v2:
- resending as patchset to make it easier to review it.
- changed commit message as requested.
- added bugzilla id.
Bugzilla ID: 228
v3:
- rework of the patchset
- caller is no longer responsible for freeing buffers on failure
- caller still has to free response buffers on success
