# \[PATCH v2 4/4\] powerpc/pseries/cpuhp: remove obsolete comment from pseries\_cpu\_die - From: Nathan Lynch \ - Date: 2021-09-27 20:22:33 - List: linuxppc-dev - Page: https://ratatoskr.run/linuxppc-dev/2021/09/9524524 - Thread: https://ratatoskr.run/linuxppc-dev/2021/09/9524522/t.md ```text This comment likely refers to the obsolete DLPAR workflow where some resource state transitions were driven more directly from user space utilities, but it also seems to contradict itself: "Change isolate state to Isolate [...]" is at odds with the preceding sentences, and it does not relate at all to the code that follows. Remove it to prevent confusion.
