System: NetBSD night-porter.duskware.de 3.99.3 NetBSD 3.99.3 (PORTER) #5: Fri May 20 12:54:13 CEST 2005 martin@night-porter.duskware.de:/usr/src/sys/arch/i386/compile/PORTER i386
Architecture: i386
Machine: i386
>Description:

The irix compat stuff uses the variable bufpages, which usualy is 0 nowadays.
The returned structure member "bufmem" is marked "not usefull" in sgi docs,
but maybe we should return something meaningfull here anyway.

>How-To-Repeat:
Code inspection

>Fix:
We could return bufmem/PAGE_SIZE, or the file cache pages, as in this patch
