Subject: [PATCH] A code cleanup change
Date: Tue, 26 Sep 2000 17:29:19 -0700 [thread overview]
Message-ID: <39D13F5F.9C7F28D6@sgi.com> (raw)
A simple change to get rid of a few magic numbers.
Not included in the patch, one could also use a simple array
for the triplet page_{min,low,high} with the same PAGE_{MIN,LOW,HIGH} index
definitions. The switch in __alloc_pages_limit will be
gone; other places will have to be modified, but
won't incur any extra cost.
Patch against test9-pre7:
