Insight into the RT Kernel Changelog

The change log will also NOT capture the changes in the RT development tree that red hat pulls for rt during this time period. .rt7.132 vs rt7.166 These are GIANT blob rewrites of the core pieces of the RT … there a HEAPS of BUG_ON() in the 8.5 kernel that are magically resolved in the 8.6 kernel. They told us they will not upgrade to 8.6 rt when i asked them to back in 2023. Looking at the RT kernel as well for 8.6 you’ll see they keep updating from rt7.166 -> rt7.189 throught the whole 8.6 process.
