[lvm-devel] LVM2 lib/config/defaults.h lib/metadata/lv.c l ...



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	agk sourceware org	2011-09-09 00:54:50

Modified files:
	lib/config     : defaults.h 
	lib/metadata   : lv.c lv.h 
	lib/report     : columns.h properties.c report.c 
	man            : lvs.8.in 

Log message:
	Add a new 'thin_pool' output field to 'lvs.
	
	A gentle reminder that anyone relying on the output of reporting commands
	like lvs in scripts must use -o to guarantee they get the fields they expect.
	
	The default sequence of fields can change from release to release.
	Equally, the 'attr' fields can have new values introduced and/or characters
	appended to them.
