I tried this way from the beginning, and to avoid redefinitions I enclose
everything in #if #endif in *.c files. I think it is not very good.
So there are two possibilities.

1. To keep it like it is now and in this way there will be quite a lot of code.
But in previous letters I gave statistics on the flush_dcache_page call in a
kernel. And our case is particular. There will not be generated a lot of code.
Or just take away inline.

2. Or it is better to carry over normal realization to *.c file and enclose
everything by one more #if #endif.

What do you consier to be better?
