From 9c3ce9ec58716733232b97771b10f31901caf62e Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Mon, 16 Feb 2015 15:59:31 -0800 Subject: ext2: get rid of most mentions of XIP in ext2 To help people transition, accept the 'xip' mount option (and report it in /proc/mounts), but print a message encouraging people to switch over to the 'dax' option.
