AI Summary: This GitHub issue requests to backport RISC-V Vector (RVV) optimizations for the xxHash algorithm into the `btrfs-progs` utility. The goal is to integrate these performance enhancements, likely originating from the standalone xxHash project, into either the upstream `btrfs-progs` repository or openEuler's fork. The change specifically targets the `crypto/xxhash.c` file within `btrfs-progs`.

AI Summary: This issue requests the backport of a RISC-V Vector (RVV) optimization for the `xxhash` package into the openEuler distribution. The optimization needs to be merged into the `2503` and `master` branches of the `xxhash` package within the `src-openeuler` Gitee repository. This task aims to enhance the performance of `xxhash` on RISC-V architectures.
