Symptoms:
	PHKL_29668:
	( SR:8606308671 CR:JAGae71705 )
	Running "fsadm -d" on VxFS 3.3 filesystem generates
	following type of errors in the message buffer:
	msgcnt 1 vxfs: mesg 003: vx_mapbad - /dev/vgXX/lvolYY
	file system free extent bitmap in au 4 marked bad.

Defect Description:
	PHKL_29668:
	( SR:8606308671 CR:JAGae71705 )
	This problem happens due to reorganization of an empty
	directory having only 1 extent with 2 blocks. When
	shrinking the directory, the code attempted to free
	the same block twice.

	Resolution:
	The empty extent with 2 blocks is now freed properly.

Enhancement:
	No
