do_migrate_pages() can return the number of pages not migrated.
Because migrate_pages() syscall return this value directly,
migrate_pages() syscall may return the number of pages not migrated.
In fail case in migrate_pages() syscall, we should return error value.
So change err to -EIO

Additionally, Correct comment above do_migrate_pages()

Thanks.

When I resend with changing -EIO to -EBUSY,
could I include "Acked-by: Michal Nazarewicz <mina86@xxxxxxxxxx>"?

Sure thing.
