John Garry <john.g.garry@oracle.com> says:
These iomap changes are spun-off the XFS large atomic writes series at
https://lore.kernel.org/linux-xfs/86a64256-497a-453b-bbba-a5ac6b4cb056@oracle.com/T/#ma99c763221de9d49ea2ccfca9ff9b8d71c8b2677
The XFS parts there are not ready yet, but it is worth having the iomap
changes queued in advance.
Some much earlier changes from that same series were already queued in the
vfs tree, and these patches rework those changes - specifically the
first patch in this series does.
The most other significant change is the patch to rework how the bio flags
are set in the DIO patch.

Flag IOMAP_ATOMIC_SW is not really required. The idea of having this flag
is that the FS ->iomap_begin callback could check if this flag is set to
decide whether to do a SW (FS-based) atomic write. But the FS can set
which ->iomap_begin callback it wants when deciding to do a FS-based
atomic write.
Furthermore, it was thought that IOMAP_ATOMIC_HW is not a proper name, as
the block driver can use SW-methods to emulate an atomic write. So change
back to IOMAP_ATOMIC.
The ->iomap_begin callback needs though to indicate to iomap core that
REQ_ATOMIC needs to be set, so add IOMAP_F_ATOMIC_BIO for that.
These changes were suggested by Christoph Hellwig and Dave Chinner.

It is neater to build blk_opf_t fully in one place, so inline
iomap_dio_bio_opflags() in iomap_dio_bio_iter().
Also tidy up the logic in dealing with IOMAP_DIO_CALLER_COMP, in generally
separate the logic in dealing with flags associated with reads and writes.

Because of the size restriction in the TCP options space, the MPTCP
ADD_ADDR option is exclusive and cannot be sent with other MPTCP ones.
For this reason, in the linked mptcp_out_options structure, group of
fields linked to different options are part of the same union.
There is a case where the mptcp_pm_add_addr_signal() function can modify
opts->addr, but not ended up sending an ADD_ADDR. Later on, back in
mptcp_established_options, other options will be sent, but with
unexpected data written in other fields due to the union, e.g. in
opts->ext_copy. This could lead to a data stream corruption in the next
packet.
Using an intermediate variable, prevents from corrupting previously
established DSS option. The assignment of the ADD_ADDR option
parameters is now done once we are sure this ADD_ADDR option can be set
in the packet, e.g. after having dropped other suboptions.

In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d2469 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping looks in atomic contexts.
Switch to the regular pointer formatting which is safer and
easier to reason about.
There are still a few users of %pK left, but these use it through seq_file,
for which its usage is safe.

The current code returns "unsigned int" and it doesn't handle errors
correctly if it happens during ioctl call for t1 delay configuration.
The ni_usb_t1_delay(), from NI, is the only function returning -1
at this point. The caller, t1_delay_ioctl(), doesn't check for errors
and sets board->t1_nano_sec to -1 and returns success.
The board->t1_nano_sec value is also used in ni_usb_setup_t1_delay()
besides the ioctl call and a value of -1 is treated as being above 1100ns.
It may or may not have a noticeable effect, but it's obviously not right
considering the content of ni_usb_setup_t1_delay().
Typical delays are in the 200-2000 range, but definitely not more
than INT_MAX so we can fix this code by changing the return type to int
and adding a check for errors. While we're at it, lets change the error
code in ni_usb_t1_delay() from -1 and instead propagate the error from
ni_usb_write_registers().

The SD spec version 6.0 section 6.4.1.5 requires that Vdd must be
lowered to less than 0.5V for a minimum of 1 ms when powering off a
card. Increase wait to 15 ms so that voltage has time to drain down
to 0.5V and cards can power off correctly. Issues with voltage drain
time were only observed on Apollo Lake and Bay Trail host controllers
so this fix is limited to those devices.

These issues trigger the warning:

Using Linux code style for gpib_board struct in .h to allow drivers to migrate.
Adhering to Linux code style.
In general, a pointer, or a struct that has elements that can reasonably be
directly accessed should never be a typedef.

If the agilent usb dongle is disconnected subsequent calls to the
driver cause a NULL dereference Oops as the bus_interface
is set to NULL on disconnect.
This problem was introduced by setting usb_dev from the bus_interface
for dev_xxx messages.
Previously bus_interface was checked for NULL only in the functions
directly calling usb_fill_bulk_urb or usb_control_msg.
Check for valid bus_interface on all interface entry points
and return -ENODEV if it is NULL.

irq allocated with devm_request_irq() will be freed in devm_irq_release(),
using free_irq() in ->remove() will causes a dangling pointer, and a
subsequent double free. So remove the free_irq() in the error path and
remove path.

There is an issue in the kernel:
In tmpfs, when using the "ls" command to list the contents
of a directory with a large number of files, glibc performs
the getdents call in multiple rounds. If a concurrent unlink
occurs between these getdents calls, it may lead to duplicate
directory entries in the ls output. One possible reproduction
scenario is as follows:
Create 1026 files and execute ls and rm concurrently:
for i in {1..1026}; do
echo "This is file $i" > /tmp/dir/file$i
done
ls /tmp/dir rm /tmp/dir/file4
->getdents(file1026-file5)
->unlink(file4)
->getdents(file5,file3,file2,file1)
It is expected that the second getdents call to return file3
through file1, but instead it returns an extra file5.
The root cause of this problem is in the offset_dir_lookup
function. It uses mas_find to determine the starting position
for the current getdents call. Since mas_find locates the first
position that is greater than or equal to mas->index, when file4
is deleted, it ends up returning file5.
It can be fixed by replacing mas_find with mas_find_rev, which
finds the first position that is less than or equal to mas->index.

The WM8904 codec supports both ADC and DMIC inputs.
Get input pin functionality from the platform data and add the necessary
controls depending on the possible additional routing.
The ADC and DMIC share the IN1L/DMICDAT1 and IN1R/DMICDAT2 pins.
This leads to a few scenarios requiring different DAPM routing:
- When both are connected to an analog input, only the ADC is used.
- When one line is a DMIC and the other an analog input, the DMIC source
is set from the platform data and a mux is added to select whether to
use the ADC or DMIC.
- When both are connected to a DMIC, another mux is added to this to
select the DMIC source. Note that we still need to be able to select
the ADC system for use with the IN2L, IN2R, IN3L and IN3R pins.
