Subject: [PATCH] don't use highmem in tcp hash size calculation
Date: Mon, 06 Nov 2006 20:06:45 -0500 [thread overview]
Message-ID: <454FDC25.6090801@psc.edu> (raw)
[-- Attachment #1: Type: text/plain, Size: 0 bytes --]
[-- Attachment #2: tcp_no_highmem.patch --]
[-- Type: text/plain, Size: 1133 bytes --]
This patch removes consideration of high memory when determining TCP hash
table sizes. Taking into account high memory results in tcp_mem values that
are too large.
