Good point!  "Simple" here means "not complex", but given the size of
this file, one could argue that this characterization is long obsolete.

I queued your patch for v5.11, but as usual could not resist the
urge to edit the commit log.  Could you please review the version
below to make sure that I did not mess anything up?

							Thanx, Paul

    list.h: Update comment to explicitly note circular lists
    
    The students in the Operating System Lecture Section at the
    American University of Sharjah were confused by the header comment
    in include/linux/list.h, which says "Simple doubly linked list
    implementation".  This comment means "simple" as in "not complex",
    but "simple" is often used in this context to mean "not circular".
    This commit therefore avoids this ambiguity by explicitly calling out
    "circular".
