What would be the vetted subset? :)
Anyway, I have now dropped the following patches that were in the 5.15.3-rc tree: bc9bbb81730e ("x86: Fix get_wchan() to support the ORC unwinder") 42a20f86dc19 ("sched: Add wrapper for get_wchan() to keep task blocked") 5d1ceb3969b6 ("x86: Fix __get_wchan() for !STACKTRACE")
And will push out another -rc release to let people test.
If there are any other commits I should have also dropped, please let me know.
thanks,
greg k-h
