-If you encounter problems with reading UDF discs using this driver,
-please report them according to MAINTAINERS file.

-Write support requires a block driver which supports writing.  Currently
-dvd+rw drives and media support true random sector writes, and so a udf
-filesystem on such devices can be directly mounted read/write.  CD-RW
-media however, does not support this.  Instead the media can be formatted
-for packet mode using the utility cdrwtool, then the pktcdvd driver can
-be bound to the underlying cd device to provide the required buffering
-and read-modify-write cycles to allow the filesystem random sector writes
-while providing the hardware with only full packet writes.  While not
-required for dvd+rw media, use of the pktcdvd driver often enhances
-performance due to very poor read-modify-write support supplied internally
-by drive firmware.

--------------------------------------------------------------------------------
-The following mount options are supported:
-
-	gid=		Set the default group.
-	umask=		Set the default umask.
-	mode=		Set the default file permissions.
-	dmode=		Set the default directory permissions.
-	uid=		Set the default user.
-	bs=		Set the block size.
-	unhide		Show otherwise hidden files.
-	undelete	Show deleted files in lists.
-	adinicb		Embed data in the inode (default)
-	noadinicb	Don't embed data in the inode
-	shortad		Use short ad's
-	longad		Use long ad's (default)
-	nostrict	Unset strict conformance
-	iocharset=	Set the NLS character set
-
-The uid= and gid= options need a bit more explaining.  They will accept a
-decimal numeric value and all inodes on that mount will then appear as
-belonging to that uid and gid.  Mount options also accept the string "forget".
-The forget option causes all IDs to be written to disk as -1 which is a way
-of UDF standard to indicate that IDs are not supported for these files .
-
-For typical desktop use of removable media, you should set the ID to that of
-the interactively logged on user, and also specify the forget option.  This way
-the interactive user will always see the files on the disk as belonging to him.
-
-The remaining are for debugging and disaster recovery:
-
-	novrs		Skip volume sequence recognition 
-
-The following expect a offset from 0.
-
-	session=	Set the CDROM session (default= last session)
-	anchor=		Override standard anchor location. (default= 256)
-	lastblock=	Set the last block of the filesystem/
