The following Python script results in unexpected behaviour when run on
a CIFS filesystem against a Windows Server:
# Create file
fd = os.open('test', os.O_WRONLY|os.O_CREAT)
os.write(fd, b'foo')
os.close(fd)
# Open and close the file to leave a pending deferred close
fd = os.open('test', os.O_RDONLY|os.O_DIRECT)
os.close(fd)
# Try to open the file via a hard link
os.link('test', 'new')
newfd = os.open('new', os.O_RDONLY|os.O_DIRECT)
The final open returns EINVAL due to the server returning
STATUS_INVALID_PARAMETER. The root cause of this is that the client
caches lease keys per inode, but the spec requires them to be related to
the filename which causes problems when hard links are involved:
From MS-SMB2 section 3.3.5.9.11:
"The server MUST attempt to locate a Lease by performing a lookup in the
LeaseTable.LeaseList using the LeaseKey in the
SMB2_CREATE_REQUEST_LEASE_V2 as the lookup key. If a lease is found,
Lease.FileDeleteOnClose is FALSE, and Lease.Filename does not match the
file name for the incoming request, the request MUST be failed with
STATUS_INVALID_PARAMETER"
On client side, we first check the context of file open, if it hits above
conditions, we first close all opening files which are belong to the same
inode, then we do open the hard link file.

A deadlock warning occurred when invoking nfs4_put_stid following a failed
dl_recall queue operation:
T1 T2
nfs4_laundromat
nfs4_get_client_reaplist
nfs4_anylock_blockers
__break_lease
spin_lock // ctx->flc_lock
spin_lock // clp->cl_lock

spin_lock // flctx->flc_lock
nfsd_break_deleg_cb
nfsd_break_one_deleg
nfs4_put_stid
refcount_dec_and_lock
spin_lock // clp->cl_lock
When a file is opened, an nfs4_delegation is allocated with sc_count
initialized to 1, and the file_lease holds a reference to the delegation.
The file_lease is then associated with the file through kernel_setlease.
The disassociation is performed in nfsd4_delegreturn via the following
call chain:
nfsd4_delegreturn --> destroy_delegation --> destroy_unhashed_deleg -->
nfs4_unlock_deleg_lease --> kernel_setlease --> generic_delete_lease
The corresponding sc_count reference will be released after this
disassociation.
Since nfsd_break_one_deleg executes while holding the flc_lock, the
disassociation process becomes blocked when attempting to acquire flc_lock
in generic_delete_lease. This means:
1) sc_count in nfsd_break_one_deleg will not be decremented to 0;
2) The nfs4_put_stid called by nfsd_break_one_deleg will not attempt to
acquire cl_lock;
3) Consequently, no deadlock condition is created.
Given that sc_count in nfsd_break_one_deleg remains non-zero, we can
safely perform refcount_dec on sc_count directly. This approach
effectively avoids triggering deadlock warnings.

nfs.ko, nfsd.ko, and lockd.ko all use crc32_le(), which is available
only when CONFIG_CRC32 is enabled. But the only NFS kconfig option that
selected CONFIG_CRC32 was CONFIG_NFS_DEBUG, which is client-specific and
did not actually guard the use of crc32_le() even on the client.
The code worked around this bug by only actually calling crc32_le() when
CONFIG_CRC32 is built-in, instead hard-coding '0' in other cases. This
avoided randconfig build errors, and in real kernels the fallback code
was unlikely to be reached since CONFIG_CRC32 is 'default y'. But, this
really needs to just be done properly, especially now that I'm planning
to update CONFIG_CRC32 to not be 'default y'.
Therefore, make CONFIG_NFS_FS, CONFIG_NFSD, and CONFIG_LOCKD select
CONFIG_CRC32. Then remove the fallback code that becomes unnecessary,
as well as the selection of CONFIG_CRC32 from CONFIG_NFS_DEBUG.

Introduce support for protocol drivers to specify whether a transfer
should use single or dual transfer mode. Currently, the SPI controller
cannot determine this information from the user, leading to potential
limitations in transfer capabilities.
Add a new field `dtr_mode` in the `spi_transfer` structure. The `dtr_mode`
field allows protocol drivers to indicate if Double Transfer Rate (DTR)
mode is supported for a given transfer. When `dtr_mode` is set to true,
the SPI controller will use DTR mode; otherwise, it will default to single
transfer mode.
Introduce another field `dtr_caps` to indicate if the QSPI controller is
capable of supporting DTR mode (SDR and DDR). By default, both `dtr_caps`
and `dtr_mode` will be false. These flags manage the QSPI controller's DTR
mode capabilities within the SPI framework.
The QSPI controller driver uses these flags to configure single or double
transfer rates using the controller register.
The existing spi-mem driver helps configure the DTR mode but is limited to
memory devices. There is no support available to set DTR mode for non-memory
devices, e.g., touch or any generic SPI sensor. This change is backward
compatible and doesn't break existing SPI or QSPI drivers.
Changes include:
- Addition of `dtr_mode` and `dtr_caps` fields in the `spi_transfer`
structure.
- Documentation updates to reflect the new `dtr_mode` and `dtr_caps` fields.

TAS2764 contains an ADC that reports the chip's die temperature.
The temperature in degrees Celsius is yielded by subtracting 93
from the raw value reported by the ADC.
Expose the codec die temperature to the hwmon interface.
The chip will initialise the temperature register to 2.6 *C
to avoid triggering over temp protection. As the ADC is powered
down during software shutdown, this value will persist until the
chip is fully powered up (e.g. when the PCM it's attached to is
opened). When the chip is powered back down, the last value sampled
will persist in the register.

TAS2770 includes an ADC which reports the chip's die temperature.
As per the datasheet, the temperature in degrees Celsius is derived
by taking the raw value stored in the ADC's registers, dividing by 16,
then subtracting 93.
Create and register a hwmon device to expose the chip's die temperature
to the hwmon interface.
The ADC is shut down during software shutdown mode, and its registers
are initialised to 0 on reset. This means that the die temperature will
read -93 *C until the chip has been fully powered up at least once (e.g.
the PCM its attached to is opened). Once the chip is put into software
shutdown again, the ADC will also shut down. The last value sampled
before this happens will persist in the ADC's registers.

Apple's SN012776 driver has some peculiar aspects to its behavior that
are suspected to work around issues in the codec part. Add a module
parameter for enabling individual quirks that should be imitated after
the Apple driver.
Setting some of these by default seems to be required. For example,
setting 0xf fixes an issue with transient overcurrent errors which
can crash the chip until the next system reboot. To be safe, let's
enable all of them by default.

We don't actually support configuring the PDM input right now. Rather,
this is useful as a hack.
On Apple Silicon machines, amps are split between two I2S buses which
are logically ANDed internally at the SoC. Odd and even slot groups are
driven by amps on either bus respectively. Since the signals are ANDed,
unused slot groups must be driven as zero to avoid corrupting the data
from the other side.
On most recent machines (TAS2764-based), this is accomplished using the
"SDOUT zero mask" feature of that chip. Unfortunately, TAS2770 does not
support this. It does support zeroing out *all* unused slots, which
works well for machines with a single amp per I2S bus. That is all,
except one.
The 13" M1 MacBook Pro is the only machine using TAS2770 and two amps
per I2S bus:
L Bus: SPK0I SPK0V Hi-Z Hi-Z SPK2I SPK2V Hi-Z Hi-Z
R Bus: Hi-Z Hi-Z SPK1I SPK2V Hi-Z Hi-Z SPK3I SPK3V
To ensure uncorrupted data, we need to force all the Hi-Z periods to
zero. We cannot use the "force all zero" feature, as that would cause a
bus conflict between both amps. We can use the pull-down feature, but
that leaves a few bits of garbage on the trailing edge of the speaker
data, since the pull-down is weak.
This is where the PDM transmit feature comes in. With PDM grounded and
disabled (the default state), the PDM slot is transmitted as all zeroes.
We can use that to force a zero 16-bit slot after the voltage data for
each speaker, cleaning it up. Then the pull-down ensures the line stays
low for the subsequent slot:
L Bus: SPK0I SPK0V PDM0 PulDn SPK2I SPK2V PDM0 PulDn
R Bus: PDM0 PulDn SPK1I SPK2V PDM0 PulDn SPK3I SPK3V
Yes, this is a horrible hack, but it beats adding dummy slots that would
be visible to the userspace capture side. There may be some other way to
fix the logical AND behavior on the MCA side... that would make this
unnecessary.
("How does Apple deal with this"? - they don't, macOS does not use
IVSENSE on TAS2770 machines even though it's physically wired up,
but we want to do so on Linux.)

Issue:
When multiple audio streams share a common BE DAI, the BE DAI

For example, the below Tegra use-case throws an error:
aplay(2 streams) -> AMX(mux) -> ADX(demux) -> arecord(2 streams),
here, 'AMX TX' and 'ADX RX' are common BE DAIs.
For above usecase when failure happens below sequence is observed:
aplay(1) FE open()
- BE DAI callbacks added to the list
- BE DAI state = SND_SOC_DPCM_STATE_OPEN
aplay(2) FE open()
- BE DAI callbacks are not added to the list as the state is

- BE DAI hw_params() callback ignored
aplay(2) FE prepare()
- Widget is powered ON without BE DAI hw_params() call
