Subject[patch 1/2] inux-2.6.9/fs/proc/base.c: array size
From domen@coderock ...
DateSat, 25 Dec 2004 16:35:12 +0100
[Sorry about duplicate, had mail problems]

Hi list,
i was looking for arrays (and possible overflows) when i noticed that
proc_pid_wchan() uses a 128-Byte array for something that can change its size
via define.

Fix possible overflow: rewrite arraysize with correct constant

re,
walter
