Linus Torvalds c8c109546a Update to zstd-1.4.10
This PR includes 5 commits that update the zstd library version:
 
 1. Adds a new kernel-style wrapper around zstd. This wrapper API
    is functionally equivalent to the subset of the current zstd API that is
    currently used. The wrapper API changes to be kernel style so that the symbols
    don't collide with zstd's symbols. The update to zstd-1.4.10 maintains the same
    API and preserves the semantics, so that none of the callers need to be
    updated. All callers are updated in the commit, because there are zero
    functional changes.
 2. Adds an indirection for `lib/decompress_unzstd.c` so it
    doesn't depend on the layout of `lib/zstd/` to include every source file.
    This allows the next patch to be automatically generated.
 3. Imports the zstd-1.4.10 source code. This commit is automatically generated
    from upstream zstd (https://github.com/facebook/zstd).
 4. Adds me (terrelln@fb.com) as the maintainer of `lib/zstd`.
 5. Fixes a newly added build warning for clang.
 
 The discussion around this patchset has been pretty long, so I've included a
 FAQ-style summary of the history of the patchset, and why we are taking this
 approach.
 
 Why do we need to update?
 -------------------------
 
 The zstd version in the kernel is based off of zstd-1.3.1, which is was released
 August 20, 2017. Since then zstd has seen many bug fixes and performance
 improvements. And, importantly, upstream zstd is continuously fuzzed by OSS-Fuzz,
 and bug fixes aren't backported to older versions. So the only way to sanely get
 these fixes is to keep up to date with upstream zstd. There are no known security
 issues that affect the kernel, but we need to be able to update in case there
 are. And while there are no known security issues, there are relevant bug fixes.
 For example the problem with large kernel decompression has been fixed upstream
 for over 2 years https://lkml.org/lkml/2020/9/29/27.
 
 Additionally the performance improvements for kernel use cases are significant.
 Measured for x86_64 on my Intel i9-9900k @ 3.6 GHz:
 
 - BtrFS zstd compression at levels 1 and 3 is 5% faster
 - BtrFS zstd decompression+read is 15% faster
 - SquashFS zstd decompression+read is 15% faster
 - F2FS zstd compression+write at level 3 is 8% faster
 - F2FS zstd decompression+read is 20% faster
 - ZRAM decompression+read is 30% faster
 - Kernel zstd decompression is 35% faster
 - Initramfs zstd decompression+build is 5% faster
 
 On top of this, there are significant performance improvements coming down the
 line in the next zstd release, and the new automated update patch generation
 will allow us to pull them easily.
 
 How is the update patch generated?
 ----------------------------------
 
 The first two patches are preparation for updating the zstd version. Then the
 3rd patch in the series imports upstream zstd into the kernel. This patch is
 automatically generated from upstream. A script makes the necessary changes and
 imports it into the kernel. The changes are:
 
 - Replace all libc dependencies with kernel replacements and rewrite includes.
 - Remove unncessary portability macros like: #if defined(_MSC_VER).
 - Use the kernel xxhash instead of bundling it.
 
 This automation gets tested every commit by upstream's continuous integration.
 When we cut a new zstd release, we will submit a patch to the kernel to update
 the zstd version in the kernel.
 
 The automated process makes it easy to keep the kernel version of zstd up to
 date. The current zstd in the kernel shares the guts of the code, but has a lot
 of API and minor changes to work in the kernel. This is because at the time
 upstream zstd was not ready to be used in the kernel envrionment as-is. But,
 since then upstream zstd has evolved to support being used in the kernel as-is.
 
 Why are we updating in one big patch?
 -------------------------------------
 
 The 3rd patch in the series is very large. This is because it is restructuring
 the code, so it both deletes the existing zstd, and re-adds the new structure.
 Future updates will be directly proportional to the changes in upstream zstd
 since the last import. They will admittidly be large, as zstd is an actively
 developed project, and has hundreds of commits between every release. However,
 there is no other great alternative.
 
 One option ruled out is to replay every upstream zstd commit. This is not feasible
 for several reasons:
 - There are over 3500 upstream commits since the zstd version in the kernel.
 - The automation to automatically generate the kernel update was only added recently,
   so older commits cannot easily be imported.
 - Not every upstream zstd commit builds.
 - Only zstd releases are "supported", and individual commits may have bugs that were
   fixed before a release.
 
 Another option to reduce the patch size would be to first reorganize to the new
 file structure, and then apply the patch. However, the current kernel zstd is formatted
 with clang-format to be more "kernel-like". But, the new method imports zstd as-is,
 without additional formatting, to allow for closer correlation with upstream, and
 easier debugging. So the patch wouldn't be any smaller.
 
 It also doesn't make sense to import upstream zstd commit by commit going
 forward. Upstream zstd doesn't support production use cases running of the
 development branch. We have a lot of post-commit fuzzing that catches many bugs,
 so indiviudal commits may be buggy, but fixed before a release. So going forward,
 I intend to import every (important) zstd release into the Kernel.
 
 So, while it isn't ideal, updating in one big patch is the only patch I see forward.
 
 Who is responsible for this code?
 ---------------------------------
 
 I am. This patchset adds me as the maintainer for zstd. Previously, there was no tree
 for zstd patches. Because of that, there were several patches that either got ignored,
 or took a long time to merge, since it wasn't clear which tree should pick them up.
 I'm officially stepping up as maintainer, and setting up my tree as the path through
 which zstd patches get merged. I'll make sure that patches to the kernel zstd get
 ported upstream, so they aren't erased when the next version update happens.
 
 How is this code tested?
 ------------------------
 
 I tested every caller of zstd on x86_64 (BtrFS, ZRAM, SquashFS, F2FS, Kernel,
 InitRAMFS). I also tested Kernel & InitRAMFS on i386 and aarch64. I checked both
 performance and correctness.
 
 Also, thanks to many people in the community who have tested these patches locally.
 If you have tested the patches, please reply with a Tested-By so I can collect them
 for the PR I will send to Linus.
 
 Lastly, this code will bake in linux-next before being merged into v5.16.
 
 Why update to zstd-1.4.10 when zstd-1.5.0 has been released?
 ------------------------------------------------------------
 
 This patchset has been outstanding since 2020, and zstd-1.4.10 was the latest
 release when it was created. Since the update patch is automatically generated
 from upstream, I could generate it from zstd-1.5.0. However, there were some
 large stack usage regressions in zstd-1.5.0, and are only fixed in the latest
 development branch. And the latest development branch contains some new code that
 needs to bake in the fuzzer before I would feel comfortable releasing to the
 kernel.
 
 Once this patchset has been merged, and we've released zstd-1.5.1, we can update
 the kernel to zstd-1.5.1, and exercise the update process.
 
 You may notice that zstd-1.4.10 doesn't exist upstream. This release is an
 artifical release based off of zstd-1.4.9, with some fixes for the kernel
 backported from the development branch. I will tag the zstd-1.4.10 release after
 this patchset is merged, so the Linux Kernel is running a known version of zstd
 that can be debugged upstream.
 
 Why was a wrapper API added?
 ----------------------------
 
 The first versions of this patchset migrated the kernel to the upstream zstd
 API. It first added a shim API that supported the new upstream API with the old
 code, then updated callers to use the new shim API, then transitioned to the
 new code and deleted the shim API. However, Cristoph Hellwig suggested that we
 transition to a kernel style API, and hide zstd's upstream API behind that.
 This is because zstd's upstream API is supports many other use cases, and does
 not follow the kernel style guide, while the kernel API is focused on the
 kernel's use cases, and follows the kernel style guide.

Pull zstd update from Nick Terrell:
 "Update to zstd-1.4.10.

  Add myself as the maintainer of zstd and update the zstd version in
  the kernel, which is now 4 years out of date, to a much more recent
  zstd release. This includes bug fixes, much more extensive fuzzing,
  and performance improvements. And generates the kernel zstd
  automatically from upstream zstd, so it is easier to keep the zstd
  verison up to date, and we don't fall so far out of date again.

  This includes 5 commits that update the zstd library version:
