Subject: [PATCH 18/34] mm: rename NR_ANON_PAGES to NR_ANON_MAPPED
Date: Fri, 8 Jul 2016 10:34:54 +0100 [thread overview]
Message-ID: <1467970510-21195-19-git-send-email-mgorman@techsingularity.net> (raw)
In-Reply-To: <1467970510-21195-1-git-send-email-mgorman@techsingularity.net>
NR_FILE_PAGES is the number of file pages.
NR_FILE_MAPPED is the number of mapped file pages.
NR_ANON_PAGES is the number of mapped anon pages.
This is unhelpful naming as it's easy to confuse NR_FILE_MAPPED and
NR_ANON_PAGES for mapped pages. This patch renames NR_ANON_PAGES so we
have
NR_FILE_PAGES is the number of file pages.
NR_FILE_MAPPED is the number of mapped file pages.
NR_ANON_MAPPED is the number of mapped anon pages.
