block: Change the type of req_op() and bio_op() into enum req_op

2022-07-14T18:14:30+00:00

Improve static type checking by changing the type of the value returned by req_op() and bio_op() from unsigned int into enum req_op. Insert 'default: break;' in switch statements on the enum req_op type to prevent that the compiler warns about these switch statements.
