Hi I'm now taking on the impossibly steep learning curve of explaining
why udf.ko can't append nonzero to two or more files in round robin
sequence.
1) I glance thru Documentation/filesystems/udf.txt
2) I start browsing http://lxr.linux.no/source/fs/udf/?v=2.6.0-test7
3) I notice udf_debug in super.c, I see we ship with that on by default
via #define UDFFS_DEBUG in udf_fs.h. I conclude already in dmesg I have
all available info, I will have to add my own printk's.
4) Maybe next I try grep write ...
Please reply to direct me past all the usual newbie pitfalls.

cd linux-2.6.0-test9/fs/udf
vi *.h
// ecma_167.h
linux/types.h may be giving us uint8_t, uint16_t etc.
VSD_STD_ID_BEA01 is the "BEA01" string of mkudffs hexdump.
// osta_udf.h
UDF_ID_DEVELOPER "*Linux UDFFS" maybe distinguishes our volumes from
others.
UDF_ID_MAC_RESOURCE "*UDF Mac ResourceFork" etc. acknowledges Mac
exists.
UDF_ID_NON_ALLOC includes the "Non-Allocatable Space" string of some
Windows views of udf discs.
Many of UDF_OS_ID_* are 0x00U but have the same suffix as distinct
UDF_OS_CLASS.
// udfdecl.h
UDF_NAME_LEN of 255, UDF_PATH_LEN of 1023, enough forever, right.
# (UDF_I_USE(inode) ... Ouch a form of C I'm too ignorant to immediately
understand.
#define UDF_PATH_LEN 1023 redundant ok why I wonder.
Here be our extern's.
// udfend.h
Prefix le maybe means little-endian.
Why endian.h is not enough I do not yet know.
// udf_i.h
// udf_sb.h
UDF_SUPER_MAGIC 0x15013346 ... hmmm ... bash of $'\x55\x41\x33\x46' is
"UA3F".

Kindly offline another linux-fsdevel newbie suggests reviewing:
A Linux CD-ROM Standard ...
12 March 1999 ...
fetched via:
$ cd Documentation/cdrom
$ cp -ip cdrom-standard.tex ~
$ cd
$ latex cdrom-standard.tex
...
$
Red Hat --> Graphics --> DVI Viewer
Pat LaVarre
P.S. When tried at my desk,
cd linux-2.6.0-test9/Documentation/cdrom
make
accomplishes something similar, launching an X viewer of a slightly
different cdrom-standard.dvi file, seemingly with help from gv` and
`gs`.
