Subject: [PATCH v2 3/9] mm: remove MPOL_MF_STATS
Date: Sun, 15 May 2011 18:20:23 -0400 [thread overview]
Message-ID: <1305498029-11677-4-git-send-email-wilsons@start.ca> (raw)
In-Reply-To: <1305498029-11677-1-git-send-email-wilsons@start.ca>
Mapping statistics in a NUMA environment is now computed using the
generic walk_page_range() logic. Remove the old/equivalent
functionality.
