Name:Mark a bio as polled. Note that for async polled IO, the caller must* expect -EWOULDBLOCK if we cannot allocate a request (or other resources).* We cannot block waiting for requests on polled IO, as those completions* must be found by the caller
Proto:static inline void bio_set_polled(struct bio *bio, struct kiocb *kiocb)
Type:void
