PREEMPT-RT is close to getting merged with the mainline Linux kernel

Noticed this article over at Phoronix:

That is potentially very good news for LinuxCNC users.

In fact, Linux has been really close to merging PREEMPT_RT into mainline for years, and most of it has been mainlined during this time. The patchset size decreased significantly as parts of it were accepted, so there has been less patching with every new release. If it decreases to 0 in 6.12, that's great! The kernel will still need to be configured to enable PREEMPT_RT and built, but that's not a problem.

Following the link to the kernel's git, Its interesting to see a string of commits about printk before the last 3 commits Phoronix mentions.
printk has been one of the most troublesome RT issues to solve so I would say that has been the enabler.
From memory printk prints error messages from the kernel to the console which is very slow and causes issues for RT
Its exciting...

Rodw was right, seems like they finally cleared the last printk/console hurdles now.
