[$] BPF and io_uring, two different ways

BPF allows programs uploaded from user space to be run, safely, within the kernel. The io_uring subsystem, too, can be thought of as a way of loading programs in the kernel, though the programs in question are mostly a sequence of I/O-related system calls. It has sometimes seemed inevitable that io_uring would, like many other parts of the kernel, gain BPF capabilities as a way of providing more flexibility to user space. That has not yet happened, but there are currently two patches sets under consideration that take different approaches to the problem.

Linux 6.19 Slated To Land "mm/cid" Rewrite That Has Very Positive Performance Potential

A set of Linux kernel patches posted back in October for rewriting the kernel's memory-mapped concurrency ID code for some nice performance wins looks like it will land for Linux 6.19. This is the code that prominent Intel engineer Thomas Gleixner found to yield up to an 18% improvement for the PostgreSQL database. My testing of this "mm/cid" code has also shown some nice performance wins too...
