The xpcs_switch_interface_mode function was introduced to handle
interface switching.
According to the XPCS datasheet, a soft reset is required to initiate
Clause 37 auto-negotiation when the XPCS switches interface modes.
When the interface mode switches from 2500BASE-X to SGMII,
re-initiating Clause 37 auto-negotiation is required for the SGMII
interface mode to function properly.

The phylink_expects_phy() function allows MAC drivers to check if they are
expecting a PHY to attach. The checking condition in phylink_expects_phy()
aims to achieve the same result as the checking condition in
phylink_attach_phy().
However, the checking condition in phylink_expects_phy() uses
pl->link_config.interface, while phylink_attach_phy() uses
pl->link_interface.
Initially, both pl->link_interface and pl->link_config.interface are set
to SGMII, and pl->cfg_link_an_mode is set to MLO_AN_INBAND.
When the interface switches from SGMII to 2500BASE-X,
pl->link_config.interface is updated by phylink_major_config().
At this point, pl->cfg_link_an_mode remains MLO_AN_INBAND, and
pl->link_config.interface is set to 2500BASE-X.
Subsequently, when the STMMAC interface is taken down
administratively and brought back up, it is blocked by
phylink_expects_phy().
Since phylink_expects_phy() and phylink_attach_phy() aim to achieve the
same result, phylink_expects_phy() should check pl->link_interface,
which never changes, instead of pl->link_config.interface, which is
updated by phylink_major_config().

====================
Permission checks for dynamic POSIX clocks
Dynamic clocks - such as PTP clocks - extend beyond the standard POSIX
clock API by using ioctl calls. While file permissions are enforced for
standard POSIX operations, they are not implemented for ioctl calls,
since the POSIX layer cannot differentiate between calls which modify
the clock's state (like enabling PPS output generation) and those that
don't (such as retrieving the clock's PPS capabilities).
On the other hand, drivers implementing the dynamic clocks lack the
necessary information context to enforce permission checks themselves.
Additionally, POSIX clock layer requires the WRITE permission even for
readonly adjtime() operations before invoking the callback.
Add a struct file pointer to the POSIX clock context and use it to
implement the appropriate permission checks on PTP chardevs. Permit
readonly adjtime() for dynamic clocks. Add a readonly option to testptp.
Changes in v4:
- Allow readonly adjtime() for dynamic clocks, as suggested by Thomas
Changes in v3:
- Reword the log message for commit against posix-clock and fix
documentation of struct posix_clock_context, as suggested by Thomas
Changes in v2:
- Store file pointer in POSIX clock context rather than fmode in the PTP
clock's private data, as suggested by Richard.
- Move testptp.c changes into separate patch.

PTP Hardware Clocks no longer require WRITE permission to perform
readonly operations, such as listing device capabilities or listening to
EXTTS events once they have been enabled by a process with WRITE
permissions.
Add '-r' option to testptp to open the PHC in readonly mode instead of
the default read-write mode. Skip enabling EXTTS if readonly mode is

Many devices implement highly accurate clocks, which the kernel manages
as PTP Hardware Clocks (PHCs). Userspace applications rely on these
clocks to timestamp events, trace workload execution, correlate
timescales across devices, and keep various clocks in sync.
The kernel’s current implementation of PTP clocks does not enforce file
permissions checks for most device operations except for POSIX clock
operations, where file mode is verified in the POSIX layer before
forwarding the call to the PTP subsystem. Consequently, it is common
practice to not give unprivileged userspace applications any access to
PTP clocks whatsoever by giving the PTP chardevs 600 permissions. An
example of users running into this limitation is documented in [1].
Additionally, POSIX layer requires WRITE permission even for readonly
adjtime() calls which are used in PTP layer to return current frequency
offset applied to the PHC.
Add permission checks for functions that modify the state of a PTP
device. Continue enforcing permission checks for POSIX clock operations
(settime, adjtime) in the POSIX layer. Only require WRITE access for
dynamic clocks adjtime() if any flags are set in the modes field.

netconsole: Add taskname sysdata support
This patchset introduces a new feature to the netconsole extradata
subsystem that enables the inclusion of the current task's name in the
sysdata output of netconsole messages.
This enhancement is particularly valuable for large-scale deployments,
such as Meta's, where netconsole collects messages from millions of
servers and stores them in a data warehouse for analysis. Engineers
often rely on these messages to investigate issues and assess kernel
health.
One common challenge we face is determining the context in which
a particular message was generated. By including the task name
(task->comm) with each message, this feature provides a direct answer to
the frequently asked question: "What was running when this message was
generated?"
This added context will significantly improve our ability to diagnose
and troubleshoot issues, making it easier to interpret output of
netconsole.
The patchset consists of seven patches that implement the following changes:
* Refactor CPU number formatting into a separate function
* Prefix CPU_NR sysdata feature with SYSDATA_
* Patch to covert a bitwise operation into boolean
* Add configfs controls for taskname sysdata feature
* Add taskname to extradata entry count
* Add support for including task name in netconsole's extra data output
* Document the task name feature in Documentation/networking/netconsole.rst
* Add test coverage for the task name feature to the existing sysdata selftest script
These changes allow users to enable or disable the task name feature via
configfs and provide additional context for kernel messages by showing
which task generated each console message.
I have tested these patches on some servers and they seem to work as
expected.

The change prepares the codebase for the upcoming taskname feature by
establishing a consistent pattern for handling sysdata features.
The CPU number formatting logic itself remains unchanged; only its
location has moved to improve maintainability.

Convert the current state assignment to use explicit boolean conversion,
making the code more robust and easier to read. This change adds a
double-negation operator to ensure consistent boolean conversion as
suggested by Paolo[1].
This approach aligns with the existing pattern used in
sysdata_cpu_nr_enabled_show().

Rename the CPU_NR enum value to SYSDATA_CPU_NR to establish a consistent
naming convention for sysdata features. This change prepares for
upcoming additions to the sysdata feature set by clearly grouping
related features under the SYSDATA prefix.
This change is purely cosmetic and does not modify any functionality.
