drbd: Drop unnecessary static
Drop static on a local variable, when the variable is initialized before any use, on every possible execution path through the function. The static has no benefit, and dropping it reduces the code size. The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @bad exists@ position p; identifier x; type T; @@ static T x@p; ... x = <+...x...+> @@ identifier x; expression e; type T; position p != bad.p; @@ -static T x@p; ... when != x when strict ?x = e; // </smpl> The change in code size is indicates by the following output from the size command. before: text data bss dec hex filename 67299 2291 1056 70646 113f6 drivers/block/drbd/drbd_nl.o after: text data bss dec hex filename 67283 2291 1056 70630 113e6 drivers/block/drbd/drbd_nl.o Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Roland Kammerer <roland.kammerer@linbit.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
