There is an inconsistent use of pr_err() statements in the current code.
Many error messages are missing the \n termination, what results in the
messages being printed with a delay, only after a next printk() line is
printed. It prevents relying on printk() to monitor the driver errors.
This patch is modifying only text messages, no functional change.

The use of two large arrays in this function makes the stack frame exceed
the warning limit in some configurations, especially with KASAN enabled.
When CONFIG_PAGE_SIZE is set to 65536, each of the arrays contains 128
pointers, so the combined size is 2KB:
fs/ntfs/mft.c: In function 'ntfs_write_mft_block.isra':
fs/ntfs/mft.c:2891:1: error: the frame size of 2640 bytes is larger than 1536 bytes [-Werror=frame-larger-than=]
Use dynamic allocation of these arrays to avoid getting into dangerously
high stack usage.
Unfortunately, allocating memory in the writepages() code path can be
problematic in case of low memory situations, so it would be better to
rework the code more widely to avoid the allocation entirely.

The presence of a sentinel (an empty {}) at the end of the ctl_table array

Deleted the empty {} from the ntfs_sysctls array to prevent

Currently, several filesystems (e.g., xfs, ext4, btrfs) implement
a "shutdown" or "going down" ioctl to simulate filesystem force a shutdown.
While they often use the same underlying numeric value, the definition is
duplicated across filesystem headers or private definitions.
Add generic definitions for FS_IOC_SHUTDOWN in uapi/linux/fs.h.
This allows new filesystems (like ntfs) to implement this feature using
a standard VFS definition and paves the way for existing filesystems
to unify their definitions later.
The flag names are standardized as FS_SHUTDOWN_* to be consistent with
the ioctl name, replacing the historical GOING_DOWN naming convention.

* Removed macros from proc handler converters
Replace the proc converter macros with "regular" functions. Though it is more
verbose than the macro version, it helps when debugging and better aligns with
coding-style.rst.
* General cleanup
Remove superfluous ctl_table forward declarations. Const qualify the
memory_allocation_profiling_sysctl and loadpin_sysctl_table arrays. Add
missing kernel doc to proc_dointvec_conv.
* Testing
This series was run through sysctl selftests/kunit test suite in

broke the core_id code needed for AMD RAPL initialization:
commit 070e92361e ("tools/power turbostat: Enhance HT enumeration")
commit ddf60e38ca ("tools/power turbostat: Simplify global core_id calculation")
Reported-by: Linus Torvalds <torvalds@linux-foundation.org>
Signed-off-by: Len Brown <len.brown@intel.com>
Since release 2025.12.02:
Add L2 statistics columns for recent Intel processors:
L2MRPS = L2 Cache M-References Per Second
L2%hit = L2 Cache Hit %
Sort work and output by cpu# rather than core#
