CVSROOT:	/cvs/lvm2
Module name:	LVM2

Modified files:
	lib/format_text: layout.h 

Log message:
	Change 'filler' to 'flags' in on-disk 'raw_locn' structure.
	
	Future patches will make use of a specific flag in the on-disk 'raw_locn'
	structure to enable/disable metadata areas, and facilitate metadata
	balancing.
	
	Note that 'filler' is always set to '0' (see add_mda() - memset),
	so use of this area as a non-zero flags field is a safe way to
	provide future code features.
