[PATCH] devfs: Remove devfs documentation from the kernel tree

		Device File System (devfs) ToDo List

			      3-JUL-2000

This is a list of things to be done for better devfs support in the

Linux kernel. If you'd like to contribute to the devfs, please have a

look at this list for anything that is unallocated. Also, if there are

items missing (surely), please contact me so I can add them to the

list (preferably with your name attached to them:-).

		Device File System (devfs) Boot Options

		Richard Gooch <rgooch@atnf.csiro.au>

			      18-AUG-2001

When CONFIG_DEVFS_DEBUG is enabled, you can pass several boot options

to the kernel to debug devfs. The boot options are prefixed by

"devfs=", and are separated by commas. Spaces are not allowed. The

syntax looks like this:

devfs=<option1>,<option2>,<option3>

and so on. For example, if you wanted to turn on debugging for module

load requests and device registration, you would do:

devfs=dmod,dreg

You may prefix "no" to any option. This will invert the option.

Debugging Options

=================

These requires CONFIG_DEVFS_DEBUG to be enabled.

Note that all debugging options have 'd' as the first character. By

default all options are off. All debugging output is sent to the

kernel logs. The debugging options do not take effect until the devfs

version message appears (just prior to the root filesystem being

mounted).

These are the options:

dmod		print module load requests to <request_module>

dreg		print device register requests to <devfs_register>

dunreg		print device unregister requests to <devfs_unregister>

dchange		print device change requests to <devfs_set_flags>

dilookup	print inode lookup requests

diget		print VFS inode allocations

diunlink	print inode unlinks

dichange	print inode changes

dimknod		print calls to mknod(2)

dall		some debugging turned on

Other Options

=============

These control the default behaviour of devfs. The options are:

mount		mount devfs onto /dev at boot time

only		disable non-devfs device nodes for devfs-capable drivers
