Hi,
There are some duplicated code when trying to merge bio from pluged list
and software queue, thus this patch set did some clean-ups when merging
a bio. Any comments are welcome. Thanks.
Changes from v1:
- Drop patch 2 and patch 5 in v1 patch set.
- Add reviewed-by tag from Christoph.
-
There are lots of duplicated code when trying to merge a bio from
plug list and sw queue, we can introduce a new helper to attempt
to merge a bio, which can simplify the blk_mq_bio_list_merge()
and blk_attempt_plug_merge().
Meanwhile move the blk_mq_bio_list_merge() into blk-merge.c and
rename it
The small blk_mq_attempt_merge() function is only called by
__blk_mq_sched_bio_merge(), just open code it.

Currently NVMe driver rejects the ZNS device if zone-append is not

Make it accept the device and activate append-emulation instead. This

It is advised to use module_name() macro instead of dereferencing mod->name

The de facto (and apparently uncommented) standard for using an mm had,
thanks to this code in sparc if nothing else, been that you must have a
reference on mm_users *and that reference must have been obtained with
mmget()*, i.e., from a thread with a reference to mm_users that had used
the mm.

Previous patches took care of the case where the master device is
pm_runtime 'suspended' when a system suspend occurs.
In the case where the master device was not suspended, e.g. if suspend
occurred while streaming audio, Intel validation noticed a race
condition: the

Add quirk and pm_runtime idle scheduling to let the Master suspend if
no Slaves become attached. This can happen when a link is not marked
as disabled and has devices exposed in the DSDT, if the power is
controlled by sideband means or the link includes a pluggable

In case the clock needs to keep running, we need to prevent the Master
from entering pm_runtime suspend.

The .prepare() callback is invoked for normal streaming, underflows or

either, but the bus parameters don't need to be recomputed.

The system resume does the entire bus re-initialization and brings it
to full-power. If the device was pm_runtime suspended, there is no
need to run the pm_runtime resume sequence after the system runtime.

This series adds power management support for Intel soundwire links.
Changes in v2:
- Move "#include " to the first required patch.
- Fit debug log in single line.

I first want to move dev_WARN_ONCE() after "if (dev)" branch, but further
I find the "if (dev)" can only be true when is_nvdimm_bus(dev) successed.
No functional change. In fact, the compiler can optimize it correctly. I
run "size drivers/nvdimm/bus.o" and find nothing has changed. So it's

I found a memleak when I learned the drivers/nvdimm code today. And I also
added a sanity check for priv->bus_desc.provider_name, because strdup()
maybe failed. Patch 3 is a trivial source code optimization.
