Linux’s ARM64 NEON Intrinsics CRC64 Code Adapted To Work On 32-bit ARM
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… ⌘ Read more

Joshua Hahn began his session in the memory-management track of the 2026 Linux Storage,\

it was not really designed for tiered-memory systems; he is looking for a
way to improve that situation. ⌘ Read more

[$] Custom page-cache policies with BPF
The kernel’s page cache is charged with maintaining pages (or, more
correctly, folios) containing copies of
data from files in the filesystem; its performance has a big effect on the
performance of the system as a whole. One of the key decisions the kernel
must make is when to evict folios from the page cache. At the 2026 Linux Storage,\

[$] Toward better handling of major page faults
A major page fault occurs when a process attempts to access a page that is
not currently present in RAM; satisfying such faults usually involves I/O, and can thus take some time. When many threads

significant lock contention while that I/O
takes place. During the memory-management track at the 2026 Linux Storage,\

[$] What is to be done about MGLRU?
“Reclaim” is the task of finding memory that can be taken away from its
current user and put to better uses within the system; it is a core part of
the memory-management picture. The addition of the multi-generational LRU (MGLRU) was meant to

[$] Improving the per-CPU memory allocator
There are many places in the kernel where performance can be improved by
