Hi Jens,
this series gets rid of the cmd_type field in struct request and
instead folds it into the REQ_OP* space. This reduces the size of
struct request, and leads to a single op namespace that drivers
can easily switch on. Except for the legacy ide driver which has
a mess of different request

This can be used to check for fs vs non-fs requests and basically
removes all knowledge of BLOCK_PC specific from the block layer,
as well as preparing for removing the cmd_type field in struct request.

Currently the legacy ide driver defines several request types of it's own,
which is in the way of removing that field entirely.
Instead add a type field to struct ide_request and use that to distinguish
the different types of IDE-internal requests.
It's a bit of a mess, but so is the surrounding
Instead of keeping two levels of indirection for requests types, fold it
all into the operations. The little caveat here is that previously
cmd_type only applied to struct request, while the request and bio op

operations.

We should not need multiple submission queues for IRQ steering.
We just need to build the cpu to vector reverse map that
blk_mq_pci_map_queues builds. So maybe we need to refactor
the API for ->map_queues a bit so that it's not tied to
submission queues. In the meantime you can just opencode

Hi all,
this is a patchset to enable full multiqueue support for the mpt3sas driver.
While the HBA only has a single mailbox register for submitting commands,
it does have individual receive queues per MSI-X interrupt and as such
does benefit from converting it to full multiqueue support.
As usua
Enable all queues and implement correct I/O steering for scsi-mq.
