[bookmark=https://twitter.com/axboe/status/1387814439597092867]Since the 5.13 io_uring bits have been merged upstream, I ran my favorite (and usual) peak performance test. Looks like 5.13 will be about 5% faster / more efficient than 5.12, 2.83M IOPS vs 3.00M for 5.13.
Just a bunch of little improvements, it all adds up in the end.[/bookmark]

Besides the usual stats on most active developers, testers and companies it this time has a section on how patches travel from developers to mainline.
Some 5.12 development statistics
By the time the 5.12 kernel was finally released, some 13,015 non-merge changesets had been pulled into the mainline repository for this development cycle. That makes 5.12 the slowest development cycle since 5.lwn.net

Toward signed BPF programs
The kernel's BPF virtual machine is versatile; it is possible to load BPF programs into the kernel to carry out a large (and growing) set of tasks. The growing body of BPF code can reasonably be thought of as kernel code in its own right.lwn.net

The TAB report on the UMN affair
The Linux Foundation Technical Advisory Board has issued its report on the submission of (intentionally and unintentionally) buggy patches from the University of Minnesota.lwn.net
It will take place 20-24 September 2021.
We also decided to stick to the same timezone as last year. You can find more details here 👇 [/bookmark]
