Subject: [PATCH 03/13] RDS: update copy_to_user state in tcp transport
Date: Thu, 11 Mar 2010 15:49:57 -0800 [thread overview]
Message-ID: <1268351407-7394-4-git-send-email-andy.grover@oracle.com> (raw)
In-Reply-To: <1268351407-7394-1-git-send-email-andy.grover@oracle.com>
Other transports use rds_page_copy_user, which updates our
s_copy_to_user counter. TCP doesn't, so it needs to explicity
call rds_stats_add().
