Subject: Re: [PATCH 1/2] Block layer filter - second version

EXPORT_SYMBOL_GPL - ok.

#ifdef CONFIG_BLK_FILTER or IS_ENABLED() - It's a matter of habit.

Looks like a candidate for ./scripts/checkpatch.pl.

I'll think about it. Personally, it seems to me that this separation
does not make it easier to understand the code. 
It is important for me to know immediately where the function is called,
and this determines its behavior.
