I don't see a point in doing ^this just to save a few characters, we're way
over the 80 columns already anyway, so wrap the long lines and span the macro
call over multiple lines.
Funny that I remember us having a discussion about macros doing string
concatenation (which I don't really mind that much) but prevents you from jumping
directly to the symbol definition - that's exactly what the QEMU alternative
does, I guess just to save some common prefixes :D.
Looking at the functions that use the typed parameters, an improvement we could
definitely do (in a standalone patch) is to ditch the index from the macro
definition since it's quite fragile, by doing:
int maxparams = X;
if (*nparams == 0) {
*nparams = maxparams;
return 0;

That's true that we're already over the 80 columns, but not by that
much so I thought that by doing it like that it allows us to "save" 13
new lines.
Funny that I remember us having a discussion about macros doing
string
concatenation (which I don't really mind that much) but prevents you from jumping
directly to the symbol definition - that's exactly what the QEMU alternative
does, I guess just to save some common prefixes :D.
Actually in this case it doesn't really prevent you. Just you need an
extra jump. One to jump to the definition of the ULL and from there to
jump to the next definition (even though all the ULL usage fits in a
single screen).
Instead if there are many (instead of a single one) strings like like
"TOTAL_BYTES_SEC", "READ_BYTES_SEC" etc that are
concatenated/extended
magically by some macro it makes it trickier to find the original
definitions. But that's just my opinion.
For me it's alright to use the QEMU macro as well, but we have already
the TEST_SET_PARAM which is used everywhere else so it makes more
sense to use it here too for consistency reasons I believe.
Looking at the functions that use the typed parameters, an improvement we could
definitely do (in a standalone patch) is to ditch the index from the macro
definition since it's quite fragile, by doing:
int maxparams = X;

That's true that we're already over the 80 columns, but not by that
much so I thought that by doing it like that it allows us to "save" 13
new lines.
Well, there isn't strictly a rule of thumb here. It's always a personal
preference, but I look at it whether we gained anything by this "translation",
we saved 13 lines, great. However, if you split the lines properly, are we
really going to lose anything? No, not even in terms of readability.

Actually in this case it doesn't really prevent you. Just you need an
extra jump. One to jump to the definition of the ULL and from there to
jump to the next definition (even though all the ULL usage fits in a

Instead if there are many (instead of a single one) strings like like
"TOTAL_BYTES_SEC", "READ_BYTES_SEC" etc that are
concatenated/extended
magically by some macro it makes it trickier to find the original
definitions. But that's just my opinion.
Ironically, patch 2 does exactly the concatenation magic ;).
For me it's alright to use the QEMU macro as well, but we have already
the TEST_SET_PARAM which is used everywhere else so it makes more
sense to use it here too for consistency reasons I believe.
I didn't object to using TEST_SET_PARAM, I merely suggested a minor adjustment
to it with other potentially necessary minor adjustments along the way.

Well, there isn't strictly a rule of thumb here. It's always a personal
preference, but I look at it whether we gained anything by this "translation",
we saved 13 lines, great. However, if you split the lines properly, are we
really going to lose anything? No, not even in terms of readability.
Okay, I see your point and it makes sense.

Ironically, patch 2 does exactly the concatenation magic ;).
Haha, well played. ;D I didn't notice / remember that. I will reply to
this on the other e-mail.
So I will resend this after removing the ULL macro.

I didn't object to using TEST_SET_PARAM, I merely suggested a minor adjustment
to it with other potentially necessary minor adjustments along the way.

I deliberately omitted the logic from qemuDomainSetBlockIoTuneDefaults
in order to leave the function simpler. I think that in the case of the
test driver it is ok.
After all, how we handle the parameters it is supposed to be
hypervisor-specific.

You should also be checking violations against the max settings, like you
mentioned in the commit note, some of the checks are hypervisor dependent, but
some are purely logical, e.g. setting one of the limits higher than the
corresponding MAX feels odd. I'm not insisting on the need to specify the limit
along the max (that really feels like per-hypervisor detail).

We've already discussed this and I believe we decided we're not going to
oncatenate the enum names, so let's do it differently in the test driver.
Haha. Alright, so I believe that in 1/2 I thought that there is a
macro that we can re-use (TEST_SET_PARAM) and re-using stuff is good.
On the other hand, for 2/2 a new macro "had to" be introduced. I
copied the one from the QEMU implementation, and indeed the macro
string concatenation done here is particularly useful because it's
used twice and with different prefixes.
So if you also think that it's fine we can probably leave it as is
here? (by removing the redundant argument of course)

Aah, right. I'll fix that.

Haha. Alright, so I believe that in 1/2 I thought that there is a
macro that we can re-use (TEST_SET_PARAM) and re-using stuff is good.
On the other hand, for 2/2 a new macro "had to" be introduced. I
copied the one from the QEMU implementation, and indeed the macro
string concatenation done here is particularly useful because it's
used twice and with different prefixes.
Although true, we should remain consistent with our decisions, even though the
macro call can be eye pleasing, we still cannot jump to the symbol directly.
It's even worse here exactly because of the two different prefixes. The reason
is the macro hides this information from you, which can only add to the
confusion when you're reading the code. Yes, it's very unfortunate that we have
to work with 2 different enums here, but I think the consistency is worth the
extra lines.
