                          *WARNING*  The loopback device will not compile
                                      with devfs 0.13.  Apply patch below.
                          *WARNING*  Some configurations will not boot
                                      with devfs 0.13.  Apply patch below.
			  *WARNING*  Your old-style sound devices will not work
                                      with devfs 0.13.  Apply patch below.
devfs-patch-0.13-fixes               Fixes the boot problem.
                                     Fixes loopback devices.
				     Fixes sound devices.

devfs-patch-0.14,
devfs-patch-0.15  -- kernel 2.1.81   Devfs 0.14 and 0.15 are functionally
                                      identical, with the exception that 
                                      0.15 has been ported to kernel 2.1.81.
                                     Version 0.14 will not work on 2.1.81 due
                                      to changes in the boot code.
				     Version 0.15 is unlikely to work on
                                      kernels earlier than 2.1.81.
                                     Floppy driver bug fix by Jurgen Botz.
                                     Loop, boot, and sound bug fixes merged
                                      from 0.13-fixes.
                                     Printer and serial improvements merged
                                      from 0.13-fixes.
                                     Fixed SCSI disc naming bug.
                                     Symlink unregistration now allowed.
devfs-patch-0.16  -- kernel 2.1.82   Created <devfs_set_symlink_destination>
                                      function, so symlinks are
				      unregistered/hidden along with
				      what the entry they point to.
                                     Moved DEVFS_SUPER_MAGIC into
 				      header file, so we can use
				      statfs(2) to determine whether a
				      file is on a devfs filesystem.
				     Added DEVFS_FL_HIDE flag.
				     Created <devfs_get_maj_min> function.
				     Created  <devfs_get_handle_from_inode>.
				     Bug fix in <find_by_dev>.
				     Major interface changes to:
				      <devfs_unregister>, <devfs_fill_file>,
				      <devfs_find_handle>.
				     Fixed inode times of symlinks.
				     Support for auto-create of pty entries.
                          *WARNING*  The 0.16 patch originally published by 
				      Richard Gooch had rejections in 
				      drivers/char/lp.c.  0.16.1 does not.
devfs-patch-0.17  -- kernel 2.1.82   Added CONFIG_DEVFS_TTY_COMPAT to 
				      accomodate broken libc's.
				     Bugfix in drivers/char/lp.c support.
				     Serial driver cleanup -- PCMCIA devices 
				      now unregister correctly.
				     Fixed non-SCSI disk registration bug.
				     Updated libc patch for ttyname().
				     All SCSI devices now registered in
				      /devfs/sg.
				     Support removal of devfs entries via 
				      unlink(2).
devfs-patch-0.18  --kernel 2.1.8[234] Added floppy/?u720 entry.
                                     Fixed kerneld support for entries in
                                      devfs subdirectories.
                                     ttyname() patch for libc updated.
                                     Documentation updates.

* There is no 0.15-0.16.1 PATCH because of differences between kernel versions
  2.1.81 and 2.1.82
