dm: cope with access beyond end of device in dm_merge_bvec If for any reason dm_merge_bvec() is given an offset beyond the end of the device, avoid an oops and always allow one page to be added to an empty bio. We'll reject the I/O later after the bio is submitted. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
