block: drop double zeroing
sg_init_table zeroes its first argument, so the allocation of that argument doesn't have to. the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x; @@ x = - kzalloc + kmalloc (...) ... sg_init_table(x,...) // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr> Signed-off-by: Jens Axboe <axboe@kernel.dk>
