You shouldn't need that.

This will cause an oops if it gets woken by a signal -- you leave and the
the 'struct erase_info' on your stack frame, which you passed to the
asynchronous erase call, goes bye bye.

+ ROOT_DEV = MKDEV(NFTL_MAJOR, 1);

Oh, I see -- if we fail to find a file system we recognise on the NOR
flash, try booting from DiskOnChip. Does this really live here?

Yes.

+mtdblock_romptr(kdev_t dev, struct vm_area_struct * vma)

No, although the fix I'm happy with is going to take a while to get
implemented so maybe in the short term. This is likely to get rejected on
other grounds anyway; perhaps separate it and don't submit it for inclusion
just now?
