CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	zkabelac sourceware org	2010-01-14 10:12:44

Modified files:
	libdm          : libdevmapper.h 

Log message:
	Cleanup gcc warning: cast from function call of type 'struct dm_list *'
	to non-matching type 'long unsigned int'
	
	Casting pointer to long and back to pointer could be easily
	handled with just pointer arithmetic.
