#   [PATCH] madvise_willneed -EIO beyond EOF
#   
#   When the rlim_rss was removed from madvise_willneed, we unintentionally
#   changed its error when applied to an area wholly beyond end of file: it
#   used to report -EIO (whereas 2.6 reports success), it currently reports
#   the confusingly inappropriate -EBADF.  Revert to -EIO in that case.
