From ee53a891f47444c53318b98dac947ede963db400 Mon Sep 17 00:00:00 2001 From: Nick Piggin Date: Tue, 6 Jan 2009 14:39:12 -0800 Subject: [PATCH] mm: do_sync_mapping_range integrity fix Chris Mason notices do_sync_mapping_range didn't actually ask for data integrity writeout. Unfortunately, it is advertised as being usable for data integrity operations. This is a data integrity bug.
