Merge tag 'erofs-for-6.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs

Pull erofs updates from Gao Xiang:
"We now support metadata compression. It can be useful for embedded use
cases or archiving a large number of small files.

Additionally, readdir performance has been improved by enabling
readahead (note that it was already common practice for ext3/4 non-dx
and f2fs directories). We may consider further improvements later to
align with ext4's s_inode_readahead_blks behavior for slow devices
too.

The remaining commits are minor.

Summary:

- Add support for metadata compression

- Enable readahead for directories to improve readdir performance

- Minor fixes and cleanups"

ASoC: Updates for v6.17

There's a few new drivers here and quite a lot of cleanup work from
Morimoto-san but generally this has been quite a quiet release,
resulting in a fairly small diffstat. Highlights include:

- Refactoring of the Kconfig menus to be hopefully more consistant and
easier to navigate.
- Refactoring of the DAPM code, mainly hiding functionality that
doesn't need to be exposed to drivers.
- Removal of the unused upstream weak paths DAPM functionality.
- Further work on the generic handling for SoundWire SDCA devices.
- Cleanups of our usage of the PM autosuspend functions, this pulls in
some PM core changes on a shared tag.
- Support for AMD ACP7.2 and SoundWire on ACP 7.1, Fairphone 4 & 5,
various Intel systems, Qualcomm QCS8275, Richtek RTQ9124 and TI TAS5753.

erofs: implement metadata compression

Thanks to the meta buffer infrastructure, metadata-compressed inodes are
just read from the metabox inode instead of the blockdevice (or backing
file) inode.

The same is true for shared extended attributes.

When metadata compression is enabled, inode numbers are divided from
on-disk NIDs because of non-LTS 32-bit application compatibility.

erofs: add on-disk definition for metadata compression

Filesystem metadata has a high degree of redundancy, so it should
compress well in the general case.

Although metadata compression can increase overall I/O latency, many
users care more about minimized image sizes than extreme runtime
performance. Let's implement metadata compression in response to user
requests [1].

Actually, it's quite simple to implement metadata compression: since
EROFS already supports per-inode compression, we can simply treat a
special inode (called `the metabox inode`) as a container for compressed
inode metadata. Since EROFS supports multiple algorithms, users can
even specify LZ4 for metadata and LZMA for data.

To better support incremental builds, the MSB of NIDs indicates where
the inode metadata is located: if bit 63 is set, the inode itself should
be read from `the metabox inode`.

Optionally, shared xattrs can also be kept in `the metabox inode` if
COMPAT_SHARED_EA_IN_METABOX is set.

Linus's R-b for patch 2. After this patchset, there is only one user of
of_gpio.h left in sound driver(pxa2xx-ac97).

of_gpio.h is deprecated, update the driver to use GPIO descriptors.

Patch 1 is to drop legacy platform data which in-tree no users are using it
Patch 2 is to convert to GPIO descriptors

Checking the DTS that use the device, all are using GPIOD_ACTIVE_LOW
polarity for reset-gpios, so all should work as expected with this patch.

Fragments aren't limited by Z_EROFS_PCLUSTER_MAX_DSIZE. However, if
a fragment's logical length is larger than Z_EROFS_PCLUSTER_MAX_DSIZE
but the fragment is not the whole inode, it currently returns
-EOPNOTSUPP because m_flags has the wrong EROFS_MAP_ENCODED flag set.
It is not intended by design but should be rare, as it can only be
reproduced by mkfs with `-Eall-fragments` in a specific case.

Let's normalize fragment m_flags using the new EROFS_MAP_FRAGMENT.

erofs: address D-cache aliasing

Flush the D-cache before unlocking folios for compressed inodes, as
they are dirtied during decompression.

Avoid calling flush_dcache_folio() on every CPU write, since it's more
like playing whack-a-mole without real benefit.

It has no impact on x86 and arm64/risc-v: on x86, flush_dcache_folio()
is a no-op, and on arm64/risc-v, PG_dcache_clean (PG_arch_1) is clear
for new page cache folios. However, certain ARM boards are affected,
as reported.
