Right, but:
1) someone with a similar but older problem might be mislead a fix is
   not for them;
2) someone with exactly this one problem (i.e. Berck ;-) might be
   mislead "no oops" is enough, while their linux might be still worse
   than before. (So I intended Berck to re-consider or even re-check
   this problem wrt. 2.6.31, and maybe even reporting another
   regression.)
