[PATCH 0/10] ide: flags query macros

[Borislav Petkov]

Hi,

this series adds the drive->atapi_flags and drive->dev_flags macro wrappers
we discussed. The idea was to make the code more readable and this has
been my main concern when coming up with the macro naming, therefore
some macro names appear a tad more descriptive than the flag itself.

Why not use a static inline here so we get proper typecheck.
And then convert the return result to a bool (0/1) so you
do not have to do this at the call site.

I counted at least three places in ide-cd that does a local
transformation to a bool and I saw nowhere the actual bit value
was used.

I'm assuming you're talking about those places (and similar):

drive->dma = !!(drive->dev_flags & IDE_DFLAG_USING_DMA);

Well, actually we almost never use the 0/1 bool value and this one
case is more of an exception. If you take a closer look, we don't have
setters/getters ..., well let's call them methods as it is in the
OO-world, and we simply access the bare flags. So the macros as such are
simply to save some stack and improve readability and since the whole
thing keeps changing we might just as well turn them into static inlines
one fine day :).

Bart, what do you think?

And in other places we do:

ide_drv_drq_int(drive) ? 1 : 0

I scanned all your patches and I did not find a single place where
the macros was not used as a bool value.
Mostly in if (ide_drv_drq_int(drive)) .. and ide_drv_drq_int(drive) &&
statements.

gcc will optmize the static inline functions so there is no drawbacks only
better type checking.

[PATCH 10/10] ide: use flags query macros in the remaining ide code

[Borislav Petkov]

Also, remove some commented out sneaked in printk's.

There should be no functionality change resulting from this patch.

...but this part destroys consistency in the process.

If you think that some flag names should be fixed please just fix them
(or just leave them alone -- I think that people invest far too much time
into fixing all these minor things while tend to fix themselves when the
big things are being fixed).

Also ide_drv_ is bad name for ->{dev,atapi}_flags (drv == "driver" for
most people not "drive") -- please make it either ide_dev_ or ide_dflag_.

Thanks,
Bart

One more thing I forgot yesterday:

Since it is not a lot of modified lines and the change is rather
straightforward it could as well be done in a single patch...

here's version 2:

From: Borislav Petkov <petkovbb@gmail.com>
Date: Mon, 23 Feb 2009 07:58:23 +0100
Subject: [PATCH] ide: flags query macros

Add drive->atapi_flags and drive->dev_flags macro wrappers

v2:
- use static inlines for better typechecking
- use macro indirection for convenience

You have a nice set of inlines to facilitate testing bits,
but not for the above use?
I guess this was not worth the abstraction for now.

Actually, that was in the v1 changelog but got forgotten. Bart, can you
please add to the changelog

- shorten >80 lines

Yeah, those are next but I'd like to wait a bit until ide rewrite
settles...

Yep, definitely an improvement.

Unfortunately my main concern is still not addressed -- namely the lack of
consistency between names of flags and names of inline functions, ie.:

-               i, (drive->dev_flags & IDE_DFLAG_NO_IO_32BIT) ? "off" : "on");
+               i, ide_dev_no_32bit_io(drive) ? "off" : "on");

This is really the major issue because introduction of this abstraction
was supposed to make code more readable and maintainable...

With the current version I get exactly the opposite feeling:
- we have now different naming used for flags and inline functions
- we use inline functions only for checking if flags are set

My other complaint is about changing my beloved CodingStyle, i.e.:

-       if (drive->media != ide_disk ||
-           (drive->dev_flags & IDE_DFLAG_PRESENT) == 0)
+       if (drive->media != ide_disk || !ide_dev_present(drive))
                select |= HT_PREFETCH_MODE;

I see '== 0' immediately while it takes a while to notice '!' (funny that
long time ago I preferred '!' because it's shorter but in the practice it
turns out to be less readable and more prone to cause subtle bugs during
code changes, though YMMV).

Also after checking the code I think ide_{d,a}flag_ naming is better
as it doesn't overlap with normal ide code...

What about printk() -> pr_info()/pr_warning()?

[ Which brings us to consistency issues again -- do you plan to convert
  whole IDE code to use pr_*()?  If yes, great but please do it in separate
  patches -- I think that converting only some printk()s is not worth it. ]

Please spend more time on documenting your changes properly.

You don't have to write a poem ;) but for reviewer it is important
to know if changes are intentional or accidental (since it could be 
as well unintentional left-over from your private tree)...

This should happen in this patch to keep the consistency, moreover since
you introduced nice macros to define "test" helpers you can now easily extend
them for "clear" ones, i.e.:

+#define IDE_AFLAG_(name, flag) \
+static inline int ide_test_aflag_##name(ide_drive_t *drive) \
+{ \
+       return !!(drive->atapi_flags & flag); \
+} \
+static inline void ide_clear_aflag_##name(ide_drive_t *drive) \
+{ \
+       drive->atapi_flags &= ~flag; \
+}

BTW you may want to delay this patch after 2.6.30 as things should
become much more peaceful then.

Thanks,
Bart

Sorry about that, will think of better names and fix.

:) this is funny, I feel the exact opposite way: If I see the "!" at the
beginning of the if-clause I just read "not" together with the function
name so for example for

if (!ide_dev_present(drive))

you have "if ide device _not_ present" or even more closely matched word
order would be "if not ide device present", well, you get the idea.
That's one of the reasons I was trying to have more readable names
for those inlines. And this way it is much more natural when reading
the code instead of "== 0" check where you still have to think a bit :).

Well, I don't know, this could just as well be a kernel janitor task.
I'll revert to printks here since there's more important stuff to do
now.

What exactly is the timeframe here? Do you want to have the updated
version for the 2.6.31 merge window?

Timeframe for 2.6.30 [1] or things becoming more peaceful [2]?

[1] We're in -rc6 so it is probably two-three more weeks before -final
    (then we have two weeks of merge window for draining ide tree queue).

[2] I think that it will happen once we finish unification of ATAPI support.

That would be ideal from my POV.
