And why 6.10? If you look at the front page of kernel.org you will see that 6.10 is now end-of-life, so why does that kernel matter to you anymore? > Those 5 fixes are needed for two reasons: maintain the consistency of > mseal's semantics across releases, and for ease of backporting future > fixes. Backporting more to 6.10? Again, it's end-of-life, who would be backporting anything else? confused, greg k-h
