Zstd Improvement For Linux 7.4 To Avoid Redundant Initialization Written by Michael Larabel in Linux Kernel on 13 September 2026 at 10:04 AM EDT. Add A Comment In addition to Usama Arif's recent Linux patches for addressing a major inefficiency within the Linux kernel's Zstd compression code, he also has a separate patch series destined for Linux 7.4 to further enhance the Zstd compression/decompression performance by avoiding redundant initialization. Usama recently posted the patches to avoid redundant cstream and dstream initialization.

Add A Comment In addition to Usama Arif's recent Linux patches for addressing a major inefficiency within the Linux kernel's Zstd compression code, he also has a separate patch series destined for Linux 7.4 to further enhance the Zstd compression/decompression performance by avoiding redundant initialization. Usama recently posted the patches to avoid redundant cstream and dstream initialization. He noticed there was an extra initialization with the first initialization being discarded without ever processing any data. With the new patches, stream initialization is deferred to the first walk iteration.
