-Changes for patch v1
-
-- creation of devfs
-
-- modified miscellaneous character devices to support devfs
-===============================================================================
-Changes for patch v2
-
-- bug fix with manual inode creation
-===============================================================================
-Changes for patch v3
-
-- bugfixes
-
-- documentation improvements
-
-- created a couple of scripts (one to save&restore a devfs and the
-  other to set up compatibility symlinks)
-
-- devfs support for SCSI discs. New name format is: sd_hHcCiIlL
-===============================================================================
-Changes for patch v4
-
-- bugfix for the directory reading code
-
-- bugfix for compilation with kerneld
-
-- devfs support for generic hard discs
-
-- rationalisation of the various watchdog drivers
-===============================================================================
-Changes for patch v5
-
-- support for mounting directly from entries in the devfs (it doesn't
-  need to be mounted to do this), including the root filesystem.
-  Mounting of swap partitions also works. Hence, now if you set
-  CONFIG_DEVFS_ONLY to 'Y' then you won't be able to access your discs
-  via ordinary device nodes. Naturally, the default is 'N' so that you
-  can still use your old device nodes.  If you want to mount from devfs
-  entries, make sure you use: append = "root=/dev/sd_..." in your
-  lilo.conf. It seems LILO looks for the device number (major&minor)
-  and writes that into the kernel image :-( 
-
-- support for character memory devices (/dev/null, /dev/zero, /dev/full
-  and so on). Thanks to C. Scott Ananian <cananian@alumni.princeton.edu>
