File 0001-BUILD-SLE12-revert-btrfs-depend-on-kernel-UAPI-inste.patch of Package containerd
From 0fda5bfa88be9b84743d5b6cfdd6e6d180089027 Mon Sep 17 00:00:00 2001
From: Aleksa Sarai <cyphar@cyphar.com>
Date: Wed, 22 May 2024 12:58:32 -0700
Subject: [PATCH] BUILD: SLE12: revert "btrfs: depend on kernel UAPI instead of
libbtrfs"
This is a partial revert of commit 52f82acb7b39 ("btrfs: depend on
kernel UAPI instead of libbtrfs"), namely switching from
github.com/containers/btrfs/v2 to v1.
On SLE 12, our UAPI headers are too old, resulting in us being unable to
build the btrfs driver with the new headers. This patch is only needed
for SLE-12.

-# Status

-
-# Dependencies
-
-## v2.x
-
-Headers from kernel 4.12 or newer.
-The package name is `linux-libc-dev` on Debian/Ubuntu, `kernel-headers` on Fedora and RHEL-like distros.
-
-The headers are only required on compilation time, not on run time.
-
-## v1.x
-
-libbtrfs headers.
-The package name is `libbtrfs-dev` on Debian/Ubuntu, `btrfs-progs-devel` on Fedora and CentOS 7.
-The package is not available for Rocky Linux and AlmaLinux.
-
-# Contribute
-
-This package may not cover all the use cases for btrfs. If something you need

-
-Note that due to struct alignment issues, this isn't yet fully native.
-Preferably, this could be resolved, so contributions in this direction are

-## Applying License Header to New Files
-
-If you submit a contribution that adds a new file, please add the license

-
-
-```console

-//
-// Additionally, all versions of the Darwin kernel from 19.6.0 through 21.2.0
-// (corresponding to MacOS 10.15.6 - 12.1) have a bug that can cause corruption
-// of the AVX512 mask registers (K0-K7) upon signal return. For this reason

-// RISC-V extension discovery code for Linux. The approach here is to first try the riscv_hwprobe
-// syscall falling back to HWCAP to check for the C extension if riscv_hwprobe is not available.
-//
-// A note on detection of the Vector extension using HWCAP.
-//
-// Support for the Vector extension version 1.0 was added to the Linux kernel in release 6.5.
-// Support for the riscv_hwprobe syscall was added in 6.4. It follows that if the riscv_hwprobe
-// syscall is not available then neither is the Vector extension (which needs kernel support).
-// The riscv_hwprobe syscall should then be all we need to detect the Vector extension.
-// However, some RISC-V board manufacturers ship boards with an older kernel on top of which
-// they have back-ported various versions of the Vector extension patches but not the riscv_hwprobe
-// patches. These kernels advertise support for the Vector extension using HWCAP. Falling
-// back to HWCAP to detect the Vector extension, if riscv_hwprobe is not available, or simply not
-// bothering with riscv_hwprobe at all and just using HWCAP may then seem like an attractive option.
-//
-// Unfortunately, simply checking the 'V' bit in AT_HWCAP will not work as this bit is used by
-// RISC-V board and cloud instance providers to mean different things. The Lichee Pi 4A board
-// and the Scaleway RV1 cloud instances use the 'V' bit to advertise their support for the unratified
-// 0.7.1 version of the Vector Specification. The Banana Pi BPI-F3 and the CanMV-K230 board use
-// it to advertise support for 1.0 of the Vector extension. Versions 0.7.1 and 1.0 of the Vector
-// extension are binary incompatible. HWCAP can then not be used in isolation to populate the
-// HasV field as this field indicates that the underlying CPU is compatible with RVV 1.0.
-//
-// There is a way at runtime to distinguish between versions 0.7.1 and 1.0 of the Vector
-// specification by issuing a RVV 1.0 vsetvli instruction and checking the vill bit of the vtype
-// register. This check would allow us to safely detect version 1.0 of the Vector extension
-// with HWCAP, if riscv_hwprobe were not available. However, the check cannot
-// be added until the assembler supports the Vector instructions.
-//
-// Note the riscv_hwprobe syscall does not suffer from these ambiguities by design as all of the
-// extensions it advertises support for are explicitly versioned. It's also worth noting that
-// the riscv_hwprobe syscall is the only way to detect multi-letter RISC-V extensions, e.g., Zba.
-// These cannot be detected using HWCAP and so riscv_hwprobe must be used to detect the majority
-// of RISC-V extensions.
-//
-// Please see https://docs.kernel.org/arch/riscv/hwprobe.html for more information.
