    block: unify flags for struct bio and struct request · 7b6d91da
    Christoph Hellwig authored
    Remove the current bio flags and reuse the request flags for the bio, too.
    This allows to more easily trace the type of I/O from the filesystem
    down to the block driver.  There were two flags in the bio that were
    missing in the requests:  BIO_RW_UNPLUG and BIO_RW_AHEAD.  Also I've
    renamed two request flags that had a superflous RW in them.
    Note that the flags are in bio.h despite having the REQ_ name - as
    blkdev.h includes bio.h that is the only way to go for now.
