Kernel release status
I know it's Valentine's Day here in the US - maybe give this release a good testing before you go back and play with development kernels. All right? Because I'm sure your SO will understand."
Headline features in 5.11 include Intel SGX support, a new system-call interception mechanism, the seccomp() constant-action bitmap optimization, the internal kmap_local() API, the epoll_pwait2() system call, and much more. See the LWN merge-window articles (part 1, part 2) and the (under development) KernelNewbies 5.11 page for more information.
