[$] A Q&A about the realtime patches

In a session at the 2023 Real Time Linux Summit, Thomas Gleixner answeredquestions about the realtime feature of the kernel, its status, and the Real-Time Linuxproject's plans for the future. The talk was billed as a "Q&A aboutPREEMPT_RT" with a caveat: "anything except printk() anddocumentation". As might be guessed, the first two questions were on justthose topics, but there were plenty of other questions (and answers) too.The summit was held in conjunction with the inaugural EmbeddedOpen Source Summit in Prague, Czechia at the end of June.
