Merged for Linux 7.1 was ARMM64 NEON-accelerated CRC64-NVMe support for around 6x the performance out of that checksumming algorithm. The generic code had been a bottleneck in NVMe and other storage subsystem code of the Linux kernel with CRC64-NVMe being used to help verify against data corruption. Now for Linux 7.2, the NEON-accelerated code will also work for those still relying on 32-bit ARM...
The continuous improvement and optimization of fundamental operating system components like the Linux kernel are an ongoing process, driven by performance demands and hardware evolution.
This development improves data integrity verification and performance for a wider range of ARM devices, especially those with 32-bit architecture, which remain prevalent in embedded systems and certain mobile contexts.
The NEON-accelerated CRC64 support, previously limited to ARM64, is now extended to 32-bit ARM systems, offering significant performance gains in checksumming for older or less powerful devices.

Improved performance and reliability for data operations on 32-bit ARM Linux systems.
Potential for broader adoption of ARM-based solutions in data-sensitive, resource-constrained environments due to enhanced integrity checks.
Slightly reduced operational costs and increased longevity for existing 32-bit ARM infrastructure by deferring hardware upgrades driven by performance bottlenecks.
