Subject: [PATCH] mm: vmstat: Do not display stats for TLB flushes unless debugging
Date: Thu, 16 Jan 2014 11:12:05 +0000 [thread overview]
Message-ID: <20140116111205.GN4963@suse.de> (raw)
In-Reply-To: <1389278098-27154-2-git-send-email-mgorman@suse.de>
The patch "x86: mm: Account for TLB flushes only when debugging" removed
vmstat counters related to TLB flushes unless CONFIG_DEBUG_TLBFLUSH was
set from the vm_event_item enum but not the vmstat_text text.
Signed-off-by: Mel Gorman <mgorman@suse.de>
