-
-
-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
