Same build failure as in 6.19.9-rc1 on my 2-socket Ivy Bridge Xeon E5-2697 v2 server:

  LD      vmlinux.unstripped
  BTFIDS  vmlinux.unstripped
WARN: resolve_btfids: unresolved symbol kthread_exit

and git revert 0507972c8244d6454cbfd242157e86bb01971bf2 (kthread: consolidate kthread exit paths to prevent 
use-after-free) makes the build error go away, but may keep the original bug the patch intended to fix?! Wentao Guan 
wrote in [1] that an additional backport is needed to make this patch work, but I didn't test this...
