Commit e6047149db ("dm: use bio op accessors") switched DM over to
using bio_set_op_attrs() but didn't take care to initialize
lc->io_req.bi_op_flags in dm-log.c:rw_header(). This caused
rw_header()'s call to dm_io() to make bio->bi_op_flags be uninitialized
in dm-io.c:do_region(), which ultimately resulted in a SCSI BUG() in
sd_init_command().
Also, adjust rw_header() and its callers to use REQ_OP_{READ|WRITE}.

presumably not actually gating any of these clocks because we were

__blk_mq_run_hw_queue() currently warns if we are running the queue on a
CPU that isn't set in its mask. However, this can happen if a CPU is
being offlined, and the workqueue handling will place the work on CPU0
instead. Improve the warning so that it only triggers if the batch cpu
in the hardware queue is currently online. If it triggers for that
case, then it's indicative of a flow problem in blk-mq, so we want to
retain it for that case.
Signed-off-by: Jens Axboe <axboe@fb.com>
We do this in a few places, if the CPU is offline. This isn't allowed,
though, since on multi queue hardware, we can't just move a request
from one software queue to another, if they map to different hardware
queues. The request and tag isn't valid on another hardware queue.
This can happen if plugging races with CPU offlining. But it does
no harm, since it can only happen in the window where we are
currently busy freezing the queue and flushing IO, in preparation
for redoing the software <-> hardware queue mappings.

Right now, for a struct, kernel-doc produces the following output:
.. c:type:: struct v4l2_prio_state
stores the priority states
**Definition**
::
struct v4l2_prio_state {
atomic_t prios[4];
};
**Members**
``atomic_t prios[4]``
array with elements to store the array priorities
Putting a member name in verbatim and adding a continuation line
causes the LaTeX output to generate something like:
item[atomic_t prios\[4\]] array with elements to store the array priorities
Everything inside "item" is non-breakable, with may produce
lines bigger than the column width.
Also, for function members, like:
int (* rx_read) (struct v4l2_subdev *sd, u8 *buf, size_t count,ssize_t *num);
It puts the name of the member at the end, like:
int (*) (struct v4l2_subdev *sd, u8 *buf, size_t count,ssize_t *num) read
With is very confusing.
The best is to highlight what really matters: the member name.
is a secondary information.
So, change kernel-doc, for it to produce the output on a different way:
**Members**
``prios[4]``
array with elements to store the array priorities
Also, as the type is not part of LaTeX "item[]", LaTeX will split it into
multiple lines, if needed.
So, both LaTeX/PDF and HTML outputs will look good.
It should be noticed, however, that the way Sphinx LaTeX output handles
things like:
Foo
bar
is different than the HTML output. On HTML, it will produce something
like:
**Foo**
bar
While, on LaTeX, it puts both foo and bar at the same line, like:
**Foo** bar

If port_guid is set with the default subnet_prefix, then we get a change
event and run a port refresh, we don't update the port_guid. As a
result, attempts to create a target device that uses the new
subnet_prefix in the wwn will fail to find a match and be rejected by
the ib_srpt driver. This makes it impossible to configure a port if it
was initialized with a default subnet_prefix and later changed to any
non-default subnet-prefix. Updating the port refresh task to always
update the wwn based upon the current subnext_prefix solves this
problem.

The v4l2_subdev_core_ops .registered_async callback was added to notify
a subdev when its entity has been registered with the media device, to
allow for example to modify the media graph (i.e: adding entities/links).
But that's not needed since there is already a .registered callback in
struct v4l2_subdev_internal_ops that's called after the entity has been
registered with the media device in v4l2_device_register_subdev().

The driver is using the struct v4l2_subdev_core_ops .registered_async
callback to register the connector entities and create the pad links
after the subdev entity has been registered with the media device.
But the .registered_async callback isn't needed since the v4l2 core
already calls the struct v4l2_subdev_internal_ops .registered callback
in v4l2_device_register_subdev(), after media_device_register_entity().
So, use the .registered() callback instead of the .registered_async()
that is going to be removed in a following patch since isn't needed.

Albeit not prohibited explicitly, re-registering sub-devices generated a
big, loud warning which quite likely soon was followed by a crash. What
followed was re-initialising a media entity, driver's registered() callback
being called and re-adding a list entry to a list.
Prevent this by returning an error if a sub-device is already registered.

Yi reported a memory leak of raid5 with DIF/DIX enabled disks. raid5
doesn't alloc/free bio, instead it reuses bios. There are two issues in
current code:
1. the code calls bio_init (from
init_stripe->raid5_build_block->bio_init) then bio_reset (ops_run_io).
The bio is reused, so likely there is integrity data attached. bio_init
will clear a pointer to integrity data and makes bio_reset can't release
the data
2. bio_reset is called before dispatching bio. After bio is finished,
it's possible we don't free bio's integrity data (eg, we don't call
bio_reset again)
Both issues will cause memory leak. The patch moves bio_init to stripe
creation and bio_reset to bio end io. This will fix the two issues.

According to its documentation, rcar_fcp_enable() returns 0 on success
or a negative error code if an error occurs. Hence
fdp1_pm_runtime_resume() and vsp1_pm_runtime_resume() forward its return
value to their callers.
However, rcar_fcp_enable() forwards the return value of
pm_runtime_get_sync(), which can actually be 1 on success, leading to
the resume failure above.
To fix this, consider only negative values returned by
pm_runtime_get_sync() to be failures.
