Subject: [Patch 05/12] GRU - delete user request for fetching chiplet status
Date: Mon, 08 Jun 2009 12:16:53 -0500 [thread overview]
Message-ID: <20090608171957.896591000@sgi.com> (raw)
In-Reply-To: <20090608171648.988318000@sgi.com>
[-- Attachment #1: uv_gru_delete_chiplet_status --]
[-- Type: text/plain, Size: 2774 bytes --]
From: Jack Steiner <steiner@sgi.com>
Delete the user request for fetching the status of a GRU chiplet.
This request has been made obsolete by other changes. Note: this
is not a change to a user API - there are no compatibility
issues with this change.
