Change 187944 by lz at gnehzuil-freebsd on 2011/01/19 07:23:26

	       Make 'mount -t ext4fs -r' can work well.
	
	       * Now we can use 'mount -t ext4fs -r /dev/XXX /YYY' to mount an ext4 file system
	         in read-only mode.
	       * Before using this command, You need to do the following steps to compile and
	         install ext4 kernel module:
	         1. enter sys/modules/ext4fs/
	         2. make && make install
	         Then you can use it to mount an ext4 file system.
	       * I don't create a new mount_ext4fs dir in sbin/ because external mount programs
	         needs to get away.
