[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [UNIKRAFT PATCH 4/7] lib/ukblkdev: blkreq.h: Use UK_BLKREQ_ prefix for states and ops
Instead of using `UK_BLKDEV_REQ_` prefix for `struct uk_blkreq`
states (finished, unfinished) and `UK_BLKDEV_` prefix for operation
requests (read, write, flush) this commits simplifies the API by using
the `UK_BLKREQ_` prefix.
