RFC: [2.6 patch] remove UMSDOS

[Adrian Bunk <bunk@fs.tum.de>]

UMSDOS in 2.6 is broken, and it seems noone needs it enough to bother 
fixing it.

I'd suggest the patch below to remove UMSDOS.

-	  Say Y here if you want to run Linux from within an existing DOS
-	  partition of your hard drive. The advantage of this is that you can
-	  get away without repartitioning your hard drive (which often implies
-	  backing everything up and restoring afterwards) and hence you're

-	  disadvantage is that Linux becomes susceptible to DOS viruses and
-	  that UMSDOS is somewhat slower than ext2fs.  Another use of UMSDOS
-	  is to write files with long unix filenames to MSDOS floppies; it
-	  also allows Unix-style soft-links and owner/permissions of files on
-	  MSDOS floppies.  You will need a program called umssync in order to
-	  make use of UMSDOS; read
-	  <file:Documentation/filesystems/umsdos.txt>.

-	  This option enlarges your kernel by about 28 KB and it only works if
-	  you said Y to both "DOS FAT fs support" and "MSDOS fs support"
-	  above.  To compile this as a module, choose M here: the module will be
-	  called umsdos.  Note that the file system of your root partition
-	  (the one containing the directory /) cannot be a module, so saying M
-	  could be dangerous.  If unsure, say N.
