This was used for completion placement for the legacy path, but for mq we have rq->mq_ctx->cpu for that. Add a helper to get the request CPU assignment, as the mq_ctx type is private to blk-mq. Reviewed-by:

With the legacy path gone, all we do is funnel it through the mq_ops->complete() operation. Tested-by:

Get rid of the special bsg job fn and timeout handler, move them into a private bsg_set instead. Mostly from Christoph, with fixes for error handling and cleanups. Reviewed-by:

The only user of legacy timing now is BSG, which is invoked from the mq timeout handler. Kill the legacy code, and rename the q->rq_timed_out_fn to q->bsg_job_timeout_fn. Reviewed-by:

Now there's no difference between blk_put_request() and __blk_put_request() anymore, get rid of the underscore version and convert the few callers. Reviewed-by:

This is a remnant of when we had ops for both SQ and MQ schedulers. Now it's just MQ, so get rid of the union. Reviewed-by:

This removes a bunch of core and elevator related code. On the core front, we remove anything related to queue running, draining, initialization, plugging, and congestions. We also kill anything related to request allocation, merging, retrieval, and completion. Remove any checking for single queue IO schedulers, as they no longer exist. This means we can also delete a bunch of code related to request issue, adding, completion, etc - and all the SQ related ops and helpers. Also kill the load_default_modules(), as all that did was provide for a way to load the default single queue elevator. Tested-by:

Now that blk_flush_queue_rq() always returns false, we can remove that return value. That bubbles through the stack, allowing us to remove a bunch of state tracking around it. Tested-by:

ide-disk and ide-cd tested as working just fine, ide-tape and ide-floppy haven't. But the latter don't require changes, so they should work without issue.

Allow the creation of conventional zones by adding the zone_nr_conv configuration attribute. This new attribute is used only for zoned devices and indicates the number of conventional zones to create. The default value is 0. Since host-managed zoned block devices must always have at least one sequential zone, if the value of zone_nr_conv is larger than or equal to the total number of zones of the device nr_zones, zone_nr_conv is automatically changed to nr_zones - 1.

Merge tag 'stratix10_dts_fix_for_v4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/dinguyen/linux into fixes ARM: dts: stratix10: fix multicast filtering On Stratix 10, the EMAC has 256 hash buckets for multicast filtering. This needs to be specified in DTS, otherwise the stmmac driver defaults to 64 buckets and initializes the filter incorrectly. As a result, e.g. valid IPv6 multicast traffic ends up being dropped. * tag 'stratix10_dts_fix_for_v4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/dinguyen/linux: arm64: dts: stratix10: fix multicast filtering Signed-off-by:
