Symptoms:
	PHCO_26252:
	( SR:8606236450 CR:JAGae05507 )
	Customer has no control over size of intent log buffers.
	VxFS file system throughput may be unduly slow.

Defect Description:
	PHCO_26252:
	( SR:8606236450 CR:JAGae05507 )
	Depending on disk characteristics, the default intent
	log buffer size could be 1k or 2k.
	Applications that do a large number of mkdir's
	may benefit from using a larger than default buffer
	size, which is much more efficient in doing disk I/O.

	Resolution:
	Add a new option to the mount command to specify
	the intent log buffer size to be 1024, 2048 or 4096.
	The new option is also documented in the mount(1m)
	man page.  In this case, users can have control over
	the size of the intent log buffer.
