Hello,

This is a repost of a patch that I posted on 9th July 2009. This time 
the patch is
for the recent dazukofs version (3.1.1).

The problem is that there is a (dazukofs_proc) structure allocated  on 
the stack and
afterwards put in a global list. This will very likely leed to problems 
sooner or later,
since the stack memory may be overwritten the next time the proc 
structure is accessed
in the list.

This patch solves this problem by using a structure that is allocated on 
the heap.

Regards,
Lino Sanfilippo
