Continuing down the pile of drivers from my RFC for making a common pool
object - we're now at nwfilter (still have storage and network to go).
For reference see patch 3 of:
http://www.redhat.com/archives/libvir-list/2017-February/msg00519.html
This series works through the nwfilter conf adjustments. We start by
fixing a couple of API's that aren't using objects, then launch into
the repetitive type actions of moving the code into it's own module,
fixing up the "style", altering the function prototypes, and finally
using virNWFilterObj prefix for any API's in virnwfilterobj.
John Ferlan (6):
conf: Change virNWFilterObjSaveDef to virNWFilterSaveDef
conf: Change virNWFilterObjDeleteDef to virNWFilterDeleteDef
conf: Introduce virnwfilterobj
conf: Adjust coding style for nwfilter conf sources
conf: Alter coding style of nwfilter function prototypes
conf: Use consistent function name prefixes for virnwfilterobj

New subject: [libvirt] [PATCH 1/6] conf: Change virNWFilterObjSaveDef to virNWFilterSaveDef
There's no need to pass the driver pointer to nwfilter_conf, just
pass the configDir.

New subject: [libvirt] [PATCH 4/6] conf: Adjust coding style for nwfilter conf sources
Alter the format of the code to follow more recent style guidelines of
two empty lines between functions, function decls with "[static] type"
on one line followed by function name with arguments to functions each
on one line.

New subject: [libvirt] [PATCH 5/6] conf: Alter coding style of nwfilter function prototypes
In an effort to be consistent with the source module, alter the function
prototypes to follow the similar style of source with the "type" on one
line followed by the function name and arguments on subsequent lines with
with argument getting it's own line.

Ouch. This is even worse than virFunction() + virFunctionInternal()
pair. Moreover, I don't think that we need virNWFilterDefLoopDetect at
all. I mean, this one starting with _ can take its place. The only
difference is that while virNWFilterDefLoopDetect() takes just two
arguments _virNWFilterDefLoopDetect() takes three.
But I guess that can be saved either for a follow up patch or one that's
inserted before this one.

Ouch. This is even worse than virFunction() + virFunctionInternal()
pair. Moreover, I don't think that we need virNWFilterDefLoopDetect at
all. I mean, this one starting with _ can take its place. The only
difference is that while virNWFilterDefLoopDetect() takes just two
arguments _virNWFilterDefLoopDetect() takes three.
Well _virNWFilterDefLoopDetect also calls itself recursively - it's a
rather nasty and ugly process from what I recall when I looked at it
while doing the RFC changes.
But I guess that can be saved either for a follow up patch or one that's
inserted before this one.
Ironically the other series did handle this... There's only one function
since lookup is handled differently.
I think I originally took the route of just changing the name of this
recursive function; however, I nixed that idea when the whole use a vir
prefix function discussion started.
I could change the name to be virNWFilterDefLoopDetectInternal in a
followup patch, but that'd perhaps only be a band-aid until I was able
to get the RFC changes into more robust patches. I can do a followup,
but it'd only be a name change...

This series works through the nwfilter conf adjustments. We start by
fixing a couple of API's that aren't using objects, then launch into
the repetitive type actions of moving the code into it's own module,
fixing up the "style", altering the function prototypes, and finally
using virNWFilterObj prefix for any API's in virnwfilterobj.

conf: Change virNWFilterObjSaveDef to virNWFilterSaveDef
conf: Change virNWFilterObjDeleteDef to virNWFilterDeleteDef
conf: Introduce virnwfilterobj
conf: Adjust coding style for nwfilter conf sources
conf: Alter coding style of nwfilter function prototypes
conf: Use consistent function name prefixes for virnwfilterobj
