Sorry for breaking this one folks..

Where this was left yesterday was to change NETCONSOLE_DYNAMIC, DLM and
OCFS2_FS symbols to use 'select configfs' instead of 'depends on SYSFS
&& CONFIGFS':

http://marc.info/?l=linux-kernel&m=129539400709508&w=2

but unfortuately this did not make it into .38-rc1 in time..

Using 'select CONFIGFS_FS' here for NETCONSOLE_DYNAMIC with the
following patches should do the trick.

   git://git.kernel.org/pub/scm/linux/kernel/git/nab/scsi-post-merge-2.6.git for-linus

Thanks,

Nicholas Bellinger (3):
  net: Make NETCONSOLE_DYNAMIC use select CONFIGFS_FS
  dlm: Make DLM use select CONFIGFS_FS
  ocfs2: Make OCFS2_FS use select CONFIGFS_FS
