Description Mark J. Cox 2005-02-16 15:45:37 UTC

Bill Rugolsky mailed Alan Cox about a trivial unprivileged local DoS.
 Linus merged this upstream with a sanitised description.

http://linux.bkbits.net:8080/linux-2.6/cset@41db2d65wbgJvuXTv4x9_quExW0vEA

This is also included in patch-2.6.10-ac8 but does not seem to appear
in RHEL4 GA or 0Day kernels.
