[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.
