It already gets fs.h indirectly through linux/mtd/super.h, so while
your patch might be correct it cannot fix a compile error.

If that's with CONFIG_BLOCK=n then it's

Otherwise please send your .config .

I do not have this config, I collect log from builds with randconfig
and try to fix problems.
It seems it is the same bug.

You must store the config of the failed builds somewhere, since
otherwise (like in this case) you cannot verify whether a patch
actually fixes a problem.
