			Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

 | ||
| ===============================================================================
 | ||
| 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>
 | ||
| ===============================================================================
 | ||
| Changes for patch v6
 | ||
| 
 | ||
| - support for subdirectories
 | ||
| 
 | ||
| - support for symbolic links (created by devfs_mk_symlink(), no
 | ||
|   support yet for creation via symlink(2))
 | ||
| 
 | ||
| - SCSI disc naming now cast in stone, with the format:
 | ||
|   /dev/sd/c0b1t2u3	controller=0, bus=1, ID=2, LUN=3, whole disc
 | ||
|   /dev/sd/c0b1t2u3p4	controller=0, bus=1, ID=2, LUN=3, 4th partition
 | ||
| 
 | ||
| - loop devices now appear in devfs
 | ||
| 
 | ||
| - tty devices, console, serial ports, etc. now appear in devfs
 | ||
|   Thanks to C. Scott Ananian <cananian@alumni.princeton.edu>
 | ||
|
