Subject: [Patch 24/25] GRU - rename gru pagesize defines
Date: Mon, 19 Jul 2010 16:32:42 -0500 [thread overview]
Message-ID: <20100719213855.017960480@sgi.com> (raw)
In-Reply-To: 20100719213651.362618144@sgi.com
[-- Attachment #1: uv_gru_min_pagesize --]
[-- Type: text/plain, Size: 1714 bytes --]
From: Jack Steiner <steiner@sgi.com>
Change the name of GRU_GSEG_PAGESIZE to GRU_MIN_GSEG_PAGESIZE
to more accurately reflect it's use. This is in preparation for
allocating contexts using hugepages.
