[PATCH v1 1/1] treewide: Align match_string() with sysfs_match_string()
Make two APIs look similar. Hence convert match_string() to be a 2-argument macro. In order to avoid unneeded churn, convert all users as well. There is no functional change intended.
Signed-off-by: Andy Shevchenko andriy.shevchenko@linux.intel.com ---
Compile tested with `make allyesconfig` and `make allmodconfig` on x86_64, arm, aarch64, powerpc64 (8 builds total).
I guess the best is to apply it to Linus' tree directly. And now it seems a good timing as there are no new users of this API either in v6.10-rcX, or in Linux Next.
But if you think differently, tell me.

I guess the best is to apply it to Linus' tree directly. And now it seems a good timing as there are no new users of this API either in v6.10-rcX, or in Linux Next.
But if you think differently, tell me.

Why do we think it's a good idea to increase and normalize the use of double-underscore function names across the kernel, like __match_string() in this case? It should mean "reserved for the implementation, not to be called directly".
If it's to be used directly, it should be named accordingly, right?
Being in line with __sysfs_match_string() isn't a great argument alone, because this adds three times the number of __match_string() calls than there are __sysfs_match_string() calls. It's not a good model to follow. Arguably both should be renamed.

Agreed. I want to get rid of any functions starting with an underscore except for those that are basically the same function used internally for convenience.
Perhaps "match_string_dynamic()"? Where it is used for dynamically allocated arrays without known size. Or, allow a third parameter for dynamic arrays.
#define match_string(_a, _s, ...) char _______STR[] = __stringify((__VA_ARGS__)); \ if (sizeof(_______STR) > 3) \ __match_string(_a, _s, ##__VA_ARGS__); \ else \ __match_string(_a, _s, ARRAY_SIZE(_a));
What the above stringify((__VA_ARGS__)) does is to check the size of any args added to match_string(). if there isn't any, it will turn into: "()\0", which is of size 3. If you add an argument, it will be: "(<arg>)\0", which will have a size greater than three.
(trace_printk() does this trick in include/linux/kernel.h).
This way, both:
match_string(array, sting);
or
match_string(array, string, size);
will work.

It's a huge mess. "__" prefix is just so ambiguous I think it just shouldn't be used or prolifierated, and it usually breaks Rusty Russells API rules times over.
Consider __set_bit() from <linux/bitops.h>, used all over the place, in contrast with set_bit() for example, what does "__" represent in this context that makes __set_bit() different from set_bit()?
It means "non-atomic"...
How does a random contributor know this?
Yeah, you guess it. By the token of "everybody knows that". (Grep, google, repeat for the number of contributors to the kernel.)
I was considering to send a script to Torvalds to just change all this to set_bit_nonatomic() (etc) but was hesitating because that makes the name unambiguous but long. I think I stayed off it because changing stuff like that all over the place creates churn and churn is bad.
Yours, Linus Walleij

nice patch, I checked some (maybe most) of your changes. There are a few unrelated changes which I don't mind, but there are two errors where the error value changes from ENODEV to EINVAL.
Find the comments through the line.

This is a logical change though, because we are changing from -ENODEV to -EINVAL. Even if it might look the right thing, but still, it's a logical change.

Compile tested with `make allyesconfig` and `make allmodconfig` on x86_64, arm, aarch64, powerpc64 (8 builds total).
I guess the best is to apply it to Linus' tree directly. And now it seems a good timing as there are no new users of this API either in v6.10-rcX, or in Linux Next.
But if you think differently, tell me.

and part of it was the naming, but there were other oddities there too.
