I can adjust those... I was more focused on the "existing" @pool and
@obj variables and didn't consider the existing @ret variables.

So while I understand the concern, my argument becomes is it technically
incorrect to change the names? Secondary to that if you're considering
multiple driver/vir*obj changes at one time, it is *far easier* to
consider an "@obj" to be that thing in the list vir*obj.c list rather
than what is either passed or gets returned from/to the consumer - a
@pool. And yes, technically a @pool is an object - I know.
The second thing that gets fixed by these changes is inconsistent usage.
For instance, prior to these changes look at testParseStorage and
testOpenVolumesForPool. The former uses @obj for a virStoragePoolObjPtr
while the latter uses @pool for a virStoragePoolObjPtr. It becomes
difficult to "follow" code with inconsistencies. So if someone takes the
effort to make things consistent - I think that's better in the long
run. Makes the code more maintainable for a reader, but yes a hassle for
someone back porting some subsequent change because of the merge conflict.
The make code more consistent wins the argument my left and right brain
have over this.
If there's not an ACK, then so be it - I can remove it, but it probably
affects subsequent patches too.
Thanks for going back to earlier series - I had partially given up on
storage and network instead focusing more on secret, nodedev, interface,
and nwfilter. I figured once I got those accepted, I could go back to
storage and network later. This just reduces that workload ;-)
