blkdev: fix merge_bvec_fn return value checks v2
merge_bvec_fn() returns bvec->bv_len on success. So we have to check against this value. But in case of fs_optimization merge we compare with wrong value. This patch must be included in b428cd6da7e6559aca69aa2e3a526037d3f20403 But accidentally i've forgot to add this in the initial patch. To make things straight let's replace all such checks. In fact this makes code easy to understand. Signed-off-by: Dmitry Monakhov <dmonakhov@openvz.org> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
