Subject: [PATCH 003 of 8] knfsd: Fix auto-sizing of nfsd request/reply buffers
Date: Fri, 29 Sep 2006 13:08:50 +1000 [thread overview]
Message-ID: <1060929030850.24050@suse.de> (raw)
In-Reply-To: 20060929130518.23919.patches@notabene
totalram is measured in pages, not bytes, so PAGE_SHIFT must be used
when trying to find 1/4096 of RAM.
