Symptoms:
	PHCO_29916:
	( SR:8606333804 CR:JAGae94891 )
	fstyp hangs on a VxFS 3.5 filesystem that has more than
	14 checkpoints.

	PHCO_28084:
	( SR:8606273970 CR:JAGae38049 )
	fstyp(1M) returns "unknown_fstyp" on VxFS version
	4 disklayout filesystem.

	( SR:8606282038 CR:JAGae45981 )
	fstyp(1M) dumps core on a VxFS version 4
	disklayout filesystem.

Defect Description:
	PHCO_29916:
	( SR:8606333804 CR:JAGae94891 )
	When fstyp command is run on VxFS 3.5 filesystem that
	has more than 14 checkpoints VxFS structural file
	(meta data) grows beyond a certain limit (has more than one
	extent) and results in fstyp command reading a particular
	block of disk, indefinitely.

	Resolution:
	The defect was in VxFS libc APIs which was fixed and
	fstyp is rebuild with the changed libc.

	PHCO_28084:
	( SR:8606273970 CR:JAGae38049 )
	fstyp(1M) results in a call to statvfsdev(), which in turn
	calls lseek().  Lseek() fails on files which are greater
	than 2GB in size, thus returning "unknown fstyp".

	Resolution:
	Makefile was modified to include the large file option.
	Now lseek64() would be called instead of lseek().
	fstyp(1M) was recompiled to make it large file aware.

	( SR:8606282038 CR:JAGae45981 )
	A "Memory fault(coredump)" might occur when the special
	device file argument passed to fstyp(1m) is of a version 4
	disklayout filesystem.

	Resolution:
	The problem was due to an uninitialized structure.  The
	structure is now correctly initialized.

Enhancement:
	No
