Fix that by adding VIR_WARNINGS_NO_STRICT_PROTOTYPES macro that uses
"GCC diagnostic push" to ignore -Wstrict-prototypes and wrapping
readline includes with it and VIR_WARNINGS_RESET.

[libvirt] [PATCH] qemu: Don't special case mdevs when assigning PCI addresses
by Andrea Bolognani
We can treat mdevs the same as all other PCI hostdevs
and figure out whether they are PCI Express or legacy PCI

[libvirt] [PATCH v2] daemon: Don't initialize SASL context if not necessary
by Peter Krempa
SASL context would be initialized even if the corresponding TCP or TLS
sockets are not enabled.
fe772f24a68 attempted to fix the symptom by commenting out the settings,
but that did not fix the root cause. 3c647ee4bbb later reverted those
changes so that the more secure algorithm is used.

[libvirt] [V3 PATCH] RFC: Reimplement cache allocation for a VM
by Eli Qiao
From: Eli Qiao <liyong.qiao(a)intel.com>
This is a RFC patch for the reimplement of `support cache tune(CAT) in
libvirt`[1].
This patch defines some structs to represent data struct in linux
resctrl fs which will be used later to do cache allocation.
The patch expose a private interface `virResctrlFreeSchemata`, which
will be used to query the cache allocation on the host.
Also added unit test cases to test this interface can works well.
There are already patch sets[2] to address it, and functional
works, but people doesn't like it cause it has global variable, and
missing unit test case for new added capabilites, etc.
Martin has proposed a test infra to do vircaps2xmltest, and I extened it
on top of it to extend resctrl control[3], this is kinds of new desiged
apart from [2], so I propose this RFC patch to do some rework on it.

[libvirt] [PATCH] util: removing dead code inside virstoragefile.
by Julio Faracco
The host address or the socket path have already been checked at the begining
of the function virStorageSourceParseNBDColonString(). So, when the parameter
is not a unix socket, there is no reason to check the address again because
if it does not exists, the logic will fail in the first IF conditional.

[libvirt] [PATCH] util: fixing wrong comparison inside virStoragePermsCopy().
by Julio Faracco
VIR_STRDUP returns -1 if the string copy was not successful. So, the current
comparison/logic is throwing an error when VIR_STRDUP() returns 1. Only when
source is NULL, it is considering as a success which is not right.
