Hugh Dickins 08259d58e4 mm: add comment on swap_duplicate's error code 
swap_duplicate()'s loop appears to miss out on returning the error code
from __swap_duplicate(), except when that's -ENOMEM.  In fact this is
intentional: prior to -ENOMEM for swap_count_continuation,
swap_duplicate() was void (and the case only occurs when copy_one_pte()
hits a corrupt pte).  But that's surprising behaviour, which certainly
deserves a comment.
