[PATCH] dm: block size bug with 64 bit devs

With 32 bit sector_t the block device size _in bytes_ is also cut to
32 bit in __set_size when the block device is mount (a filesystem
mounted). The argument should be cast to loff_t before expanding the
sector count to a byte count and calling i_size_write.
