As said by Linus:
A symmetric naming is only helpful if it implies symmetries in use.
Otherwise it's actively misleading.
In "kzalloc()", the z is meaningful and an important part of what the
caller wants.
In "kzfree()", the z is actively detrimental, because maybe in the
future we really _might_ want to use that "memfill(0xdeadbeef)" or
something. The "zero" part of the interface isn't even _relevant_.
The main reason that kzfree() exists is to clear sensitive information
that should not be leaked to other future users of the same memory
objects.
Rename kzfree() to kfree_sensitive() to follow the example of the recently
added kvfree_sensitive() and make the intention of the API more explicit.
In addition, memzero_explicit() is used to clear the memory to make sure
that it won't get optimized away by the compiler.
The renaming is done by using the command sequence:
git grep -w --name-only kzfree |\
xargs sed -i 's/kzfree/kfree_sensitive/'
followed by some editing of the kfree_sensitive() kerneldoc and adding
a kzfree backward compatibility macro in slab.h.

Here is the large set of Staging and IIO driver patches for 5.9-rc1.
Lots of churn here, but overall the size increase in lines added is
small, while adding a load of new IIO drivers.
Major things in here:
- lots and lots of IIO new drivers and frameworks added
- IIO driver fixes and updates
- lots of tiny coding style cleanups for staging drivers
- vc04_services major reworks and cleanups
We had 3 set of drivers move out of staging in this round as well:
- wilc1000 wireless driver moved out of staging
- speakup moved out of staging
- most USB driver moved out of staging
Full details are in the shortlog.
All of these have been in linux-next with no reported issues. The last

static priority level knowledge from non-scheduler code.
The three APIs for non-scheduler code to set SCHED_FIFO are:
- sched_set_fifo()
- sched_set_fifo_low()
- sched_set_normal()
These are two FIFO priority levels: default (high), and a 'low' priority level,
plus sched_set_normal() to set the policy back to non-SCHED_FIFO.
Since the changes affect a lot of non-scheduler code, we kept this in a separate
tree.
When merging to the latest upstream tree there's a conflict in drivers/spi/spi.c,
which can be resolved via:
sched_set_fifo(ctlr->kworker_task);

The pointer header is an alias to msg and msg is being null checked.
However, if msg is null then header is also null and this can lead to
a null pointer dereference on the assignment type = header->type. Fix
this just using header->type after the null check and removing the need
for type as it is only used once.

syzbot report [1] describes a deadlock when write operation against an
ashmem fd executed at the time when ashmem is shrinking its cache results
in the following lock sequence:
Possible unsafe locking scenario:
CPU0 CPU1
---- ----
lock(fs_reclaim);
lock(&sb->s_type->i_mutex_key#13);
lock(fs_reclaim);
lock(&sb->s_type->i_mutex_key#13);
kswapd takes fs_reclaim and then inode_lock while generic_perform_write
takes inode_lock and then fs_reclaim. However ashmem does not support
writing into backing shmem with a write syscall. The only way to change
its content is to mmap it and operate on mapped memory. Therefore the race
that lockdep is warning about is not valid. Resolve this by introducing a
separate lockdep class for the backing shmem inodes.

This converts all the existing DECLARE_TASKLET() (and ...DISABLED)
macros with DECLARE_TASKLET_OLD() in preparation for refactoring the
tasklet callback type. All existing DECLARE_TASKLET() users had a "0"
data argument, it has been removed here as well.

Make use of the flex_array_size() helper to calculate the size of a
flexible array member within an enclosing structure.
This helper offers defense-in-depth against potential integer
overflows, while at the same time makes it explicitly clear that
we are dealing with a flexible array member.

Currently you can't enable the Gey Bus Audio Codec because there is no
entry for it in the Kconfig file. Originally the config name was going
to be AUDIO_MSM8994 but that's not correct because other types of
hardware are supported now. I have chosen the name AUDIO_APB_CODEC
instead. Also I had to update the dependencies for GREYBUS_AUDIO to
make the compile work.

Greybus Codec driver allows modules to be dynamically added and removed,
which further requires updating the DAPM configurations as well.
With current snd_soc architecture, dynamic audio modules is not yet
supported. This patch provides helper APIs to update DAPM configurations
in response to modules which are dynamically added or removed. The
source is primarily based on snd_dapm.c

As per the current implementation for GB codec driver, a jack list is
maintained for each module. And it expects the list to be populated by
the snd_soc_jack structure which would require modifications in
mainstream code.
However, this is not a necessary requirement and the list can be easily
maintained within gbaudio_module_info as well. This patch provides the
relevant changes for the same.

Drivers using legacy power management .suspen()/.resume() callbacks
have to manage PCI states and device's PM states themselves. They also
need to take care of standard configuration registers.
Switch to generic power management framework using a single
"struct dev_pm_ops" variable to take the unnecessary load from the driver.
This also avoids the need for the driver to directly call most of the PCI
helper functions and device power state control functions, as through
the generic framework PCI Core takes care of the necessary operations,
and drivers are required to do only device-specific jobs.

The variable authmode can be uninitialized. The danger would be if
it equals to _WPA_IE_ID_ (0xdd) or _WPA2_IE_ID_ (0x33). We can avoid
this by setting it to zero instead. This is the approach that was
used in the rtl8723bs driver.

Thanks to Okash's latest work, the TODO list is essentially empty, so
the way out from staging now seems open.
The status of the remaining issue mentioned in TODO is not clear, we
asked the speakup user mailing list for reproducer cases, but didn't get
a really specific scenario. One serious bug was fixed by 9d32c0cde4
("staging/speakup: fix get_word non-space look-ahead"), which does not
seem to really be related to the bug mentioned in TODO. Possibly the bug
mentioned in TODO has been fixed long ago and people have been thinking
that it was not because they can not distinguish the symptoms mentioned
in TODO from the symptoms of the bug fixed by 9d32c0cde4.
