Description Adam 2004-08-04 10:41:03 UTC

I tried to exclude devfs from the kernel by unchecking the "/dev file system support" option, because I recently installed udev and want to switch to it.  When trying to build the kernel afterwards, the following bunch of warnings appeared:

WARNING: /lib/modules/2.6.5-gentoo-r1/misc/svgalib_helper.ko needs unknown symbol devfs_mk_dir
WARNING: /lib/modules/2.6.5-gentoo-r1/misc/svgalib_helper.ko needs unknown symbol devfs_mk_cdev
WARNING: /lib/modules/2.6.5-gentoo-r1/misc/svgalib_helper.ko needs unknown symbol devfs_mk_symlink
WARNING: /lib/modules/2.6.5-gentoo-r1/misc/svgalib_helper.ko needs unknown symbol devfs_remove
WARNING: /lib/modules/2.6.5-gentoo-r1/video/nvidia.ko needs unknown symbol devfs_mk_cdev
WARNING: /lib/modules/2.6.5-gentoo-r1/video/nvidia.ko needs unknown symbol devfs_remove

The filenames and the emerge info as well as the heading when I go into "make menuconfig" seem to suggest that I'm using a 2.6.5 kernel, so I believe that's my kernel version.  But for some reason my version of "gentoo-dev-sources" is 2.6.7-r11.  I don't know why it isn't switching, but that's another issue.


Reproducible: Always
Steps to Reproduce:
1.Install udev
2.Start "make menuconfig"
3.Deselect the devfs option
4.Build the kernel

Actual Results:  
The above warnings were printed.

Expected Results:  
No warnings printed.

I tried removing devfs from the kernel in version 2.6.8 now, and the svgalib_helper.ko warnings went away; only the nvidia.ko warnings remained.  Since I believe nvidia is a closed source driver, I guess there's nothing you guys can do about it if it requires devfs to be in the kernel (I can use nvidia without starting devfs, though).  So I'm changing this bug to CANTFIX.
