I will recheck, because in v6.0 I don't see anything, but LKP was not okay with something IIRC. -- With Best Regards, Andy Shevchenko

That matches what I would expect to see given the content of the text. And for me vim also gives the original order. Just to confirm - is '.' 0x2e and '/' 0x2f in your universe? Cheers, Kent.

Currently I have en_US.UTF-8. Throwing my can of paint into the mix... I think it is more logical to first include the general <linux/gpio.h>, followed by whatever <linux/gpio-foo.h> and <linux/gpio/bar.h>, irrespective of (language-specific or phonebook) sort order. Yeah, it sucks that this requires some manual work after running sort...

It seems that kind of issue is in this patch only.

After all this patch is not needed. However, during checking of the necessity
of this patch I realized that seq_file is used in a few GPIO drivers without
any actual users, so I will prepare clean up series for that as well.

Eventually I can answer to your question: the commit 0ae3109a8391 ("gpiolib: cdev: add fdinfo output for line request file descriptors") is what you are missing. That said, we need this patch.

Do not imply that some of the generic headers may be always included. Instead, include explicitly what we are direct user of. While at it, sort headers alphabetically.
