[lvm-devel] LVM2 ./WHATS_NEW_DM libdm/mm/pool-fast.c



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	zkabelac sourceware org	2011-10-23 15:38:03

Modified files:
	.              : WHATS_NEW_DM 
	libdm/mm       : pool-fast.c 

Log message:
	Fix usage of DEBUG_ENFORCE_POOL_LOCKING with DEBUG_MEM
	
	Since DEBUG_MEM is storing own extra structure within returned memory chunk,
	glibc free must be used directly for posix_memaling() allocated block.
