A single line break should be put into a sequence. Thus use the
corresponding function "seq_putc".

We encounter the above issue after commit 2eea9ce4310d ("mounts: keep

rbtree.
So we can instead use rbtree to iterate all mounts information.

Recently, I saw a patch[1] on the ext4 mailing list regarding
the correction of a macro definition error. Jan mentioned
that "The bug in the macro is a really nasty trap...".
Because existing compilers are unable to detect
unused parameters in macro definitions. This inspired me
to write a script to check for unused parameters in
macro definitions and to run it.
Surprisingly, the script uncovered numerous issues across
various subsystems, including filesystems, drivers, and sound etc.
Some of these issues involved parameters that were accepted
but never used, for example:
#define XFS_DAENTER_DBS(mp,w) \
(XFS_DA_NODE_MAXDEPTH + (((w) == XFS_DATA_FORK) ? 2 : 0))
where mp was unused.
While others are actual bugs.
For example:
#define HAL_SEQ_WCSS_UMAC_CE0_SRC_REG(x) \
(ab->hw_params.regs->hal_seq_wcss_umac_ce0_src_reg)
#define HAL_SEQ_WCSS_UMAC_CE0_DST_REG(x) \
(ab->hw_params.regs->hal_seq_wcss_umac_ce0_dst_reg)
#define HAL_SEQ_WCSS_UMAC_CE1_SRC_REG(x) \
(ab->hw_params.regs->hal_seq_wcss_umac_ce1_src_reg)
#define HAL_SEQ_WCSS_UMAC_CE1_DST_REG(x) \
(ab->hw_params.regs->hal_seq_wcss_umac_ce1_dst_reg)
where x was entirely unused, and instead, a local variable ab was used.
I have submitted patches[2-5] to fix some of these issues,
but due to the large number, many still remain unaddressed.
I believe that the kernel and matainers would benefit from
this script to check for unused parameters in macro definitions.
It should be noted that it may cause some false positives
in conditional compilation scenarios, such as
#ifdef DEBUG
static int debug(arg) {};
#else
#define debug(arg)
#endif
So the caller needs to manually verify whether it is a true
issue. But this should be fine, because Maintainers should only
need to review their own subsystems, which typically results
in only a few reports.

XZ_EXTERN was used to make internal functions static in the preboot code.
However, in other decompressors this hasn't been done. On x86-64, this
makes no difference to the kernel image size.
Omit XZ_EXTERN and let some of the internal functions be extern in the
preboot code. Omitting XZ_EXTERN from include/linux/xz.h fixes warnings
in "make htmldocs" and makes the intradocument links to xz_dec functions
work in Documentation/staging/xz.rst. The alternative would have been to
add "XZ_EXTERN" to c_id_attributes in Documentation/conf.py but omitting
XZ_EXTERN seemed cleaner.

Use LZMA2 options that match the arch-specific alignment of instructions.
This change reduces compressed kernel size 0-2 % depending on the arch.
On 1-byte-aligned x86 it makes no difference and on 4-byte-aligned archs
it helps the most.
Use the ARM-Thumb filter for ARM-Thumb2 kernels. This reduces compressed
kernel size about 5 %.[1] Previously such kernels were compressed using
the ARM filter which didn't do anything useful with ARM-Thumb2 code.
Add BCJ filter support for ARM64 and RISC-V. Compared to unfiltered XZ or
plain LZMA, the compressed kernel size is reduced about 5 % on ARM64 and 7
% on RISC-V. A new enough version of the xz tool is required: 5.4.0 for
ARM64 and 5.6.0 for RISC-V. With an old xz version, a message is printed
to standard error and the kernel is compressed without the filter.
Update lib/decompress_unxz.c to match the changes to xz_wrap.sh.
Update the CONFIG_KERNEL_XZ help text in init/Kconfig:
- Add the RISC-V and ARM64 filters.
- Clarify that the PowerPC filter is for big endian only.
- Omit IA-64.

This only affects kernel image compression, not any other xz usage.
Desktop kernels on x86-64 are already around 60 MiB. Using a dictionary
larger than 32 MiB should have no downsides nowadays as anyone building
the kernel should have plenty of RAM. 128 MiB dictionary needs 1346 MiB
of RAM with xz versions 5.0.x - 5.6.x in single-threaded mode. On archs
that use xz_wrap.sh, kernel decompression is done in single-call mode so a
larger dictionary doesn't affect boot-time memory requirements.
xz >= 5.6.0 uses multithreaded mode by default which compresses slightly
worse than single-threaded mode. Kernel compression rarely used more than
one thread anyway because with 32 MiB dictionary size the default block
size was 96 MiB in multithreaded mode. So only a single thread was used
anyway unless the kernel was over 96 MiB.
Comparison to CONFIG_KERNEL_LZMA: It uses "lzma -9" which mapped to 32 MiB
dictionary in LZMA Utils 4.32.7 (the final release in 2008). Nowadays the
lzma tool on most systems is from XZ Utils where -9 maps to 64 MiB
dictionary. So using a 32 MiB dictionary with CONFIG_KERNEL_XZ may have
compressed big kernels slightly worse than the old LZMA option.
Comparison to CONFIG_KERNEL_ZSTD: zstd uses 128 MiB dictionary.

In 2018, a dependency on <linux/crc32poly.h> was added to avoid
duplicating the same constant in multiple files. Two months later it was
found to be a bad idea and the definition of CRC32_POLY_LE macro was moved
into xz_private.h to avoid including <linux/crc32poly.h>.
xz_private.h is a wrong place for it too. Revert back to the upstream
version which has the poly in xz_crc32_init() in xz_crc32.c.

count as a BSD license variant here.
The switch to 0BSD was done in the upstream XZ Embedded project because
public domain has (real or perceived) legal issues in some jurisdictions.

Patch series "xz: Updates to license, filters, and compression options",
v2.
XZ Embedded, the upstream project, switched from public domain to the BSD
Zero Clause License (0BSD). Now matching SPDX license identifiers can be
added.
Documentation was revised. Fix syntax errors in kernel-doc comments in
<linux/xz.h>. The xz_dec API docs from <linux/xz.h> are now included in
Documentation/staging/xz.rst.
The new ARM64 and RISC-V filters can be used for kernel decompression if
CONFIG_EFI_ZBOOT=y. The filters can be used by Squashfs too. (Userspace
Squashfs-tools already had the ARM64 filter support committed but it was
reverted due to backdoor fears. I try to get ARM64 and RISC-V filter
support added to Squashfs-tools somewhat soon.)
Account for the default threading change made in the xz command line tool
version 5.6.0. Tweak kernel compression options for archs that support XZ
compressed kernel.
This patch (of 16):
I have been the maintainer of the upstream project since I submitted the
code to Linux in 2010 but I forgot to add myself to MAINTAINERS.

This bug has existed since the initial OCFS2 code. The code logic in
ocfs2_sync_local_to_main() is wrong, as it ignores the last contiguous
free bits, which causes an OCFS2 volume to lose the last free clusters of
LA window on each umount command.

Patch series "mul_u64_u64_div_u64: new implementation", v3.
This provides an implementation for mul_u64_u64_div_u64() that always
produces exact results.
This patch (of 2):
Library facilities must always return exact results. If the caller may be
contented with approximations then it should do the approximation on its
own.
In this particular case the comment in the code says "the algorithm
... below might lose some precision". Well, if you try it with e.g.:
a = 18446462598732840960
b = 18446462598732840960
c = 18446462598732840961
then the produced answer is 0 whereas the exact answer should be
18446462598732840959. This is _some_ precision lost indeed!
Let's reimplement this function so it always produces the exact result
regardless of its inputs while preserving existing fast paths when
possible.
Uwe said:
: My personal interest is to get the calculations in pwm drivers right.
: This function is used in several drivers below drivers/pwm/ . With the
: errors in mul_u64_u64_div_u64(), pwm consumers might not get the
: settings they request. Although I have to admit that I'm not aware it
: breaks real use cases (because typically the periods used are too short
: to make the involved multiplications overflow), but I pretty sure am
: not aware of all usages and it breaks testing.
:
: Another justification is commits like
: https://git.kernel.org/tip/77baa5bafcbe1b2a15ef9c37232c21279c95481c,
: where people start to work around the precision shortcomings of
: mul_u64_u64_div_u64().

We had a report of data corruption on nixos when building installer
images.
https://github.com/NixOS/nixpkgs/pull/321055#issuecomment-2184131334
It seems that writes are being dropped, but only when issued by QEMU,
and possibly only in snapshot mode. It's undetermined if it's write
calls are being dropped or dirty folios.
Further testing, via minimizing the original patch to just the change
that skips the inode lock on non appends/truncates, reveals that it
really is just not taking the inode lock that causes the corruption: it
has nothing to do with the other logic changes for preserving write
atomicity in corner cases.
It's also kernel config dependent: it doesn't reproduce with the minimal
kernel config that ktest uses, but it does reproduce with nixos's distro
config. Bisection the kernel config initially pointer the finger at page
migration or compaction, but it appears that was erroneous; we haven't
yet determined what kernel config option actually triggers it.
Sadly it appears this will have to be reverted since we're getting too
close to release and my plate is full, but we'd _really_ like to fully
debug it.
My suspicion is that this patch is exposing a preexisting bug - the
inode lock actually covers very little in IO paths, and we have a
different lock (the pagecache add lock) that guards against races with
truncate here.
