There are a number of make_request based drivers which dont support
cache flushes. Filter out flush bios in __generic_make_request() so
that they dont have to worry about them. All FLUSH/FUA reques |

Hello, Jens.

Currently __blk_rq_prep_clone() copies only REQ_WRITE and REQ_DISCARD.

Remove now unused REQ_HARDBARRIER support. virtio_blk already
supports REQ_FLUSH and the usefulness of REQ_FUA for virtio_blk is
questionable at this point, so theres nothing else to do to support

Unplugging from a request function doesnt really help much (its
already in the request_fn) and soon block layer will be updated to mix
barrier sequence with other commands, so theres no need to treat |
