| =============================================================================== | |
| 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> | |
| =============================================================================== | |

| /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> | |

| devfs devices | |
| - increased NR_SUPER to 128 to support large numbers of devfs mounts | |
| (for chroot(2) gaols) | |
| - fixed bug in SCSI disc support: was generating incorrect minors if | |
| SCSI ID's did not start at 0 and increase by 1 | |
| - support symlink traversal when mounting root | |
| =============================================================================== | |
| Changes for patch v13 | |
| - added devfs support to soundcard driver | |

| devfs entries for SCSI disc partitions which actually exist | |
