How to disable configfs_example modules

How to disable configfs_example modules

[Jaswinder Singh Rajput]

Hello Randy,

I am trying to build no modules but unfortunately I am getting 3 modules
with http://userweb.kernel.org/~jaswinder/Corei7/config-i7-64.txt :

  INSTALL Documentation/filesystems/configfs/configfs_example_explicit.ko
  INSTALL Documentation/filesystems/configfs/configfs_example_macros.ko
  INSTALL drivers/scsi/scsi_wait_scan.ko

How can I get rid of configfs_example modules.

What is the magic in 'ifneq ($(CONFIG_CONFIGFS_FS),)' :

Documentation/filesystems/configfs/Makefile :
ifneq ($(CONFIG_CONFIGFS_FS),)
obj-m += configfs_example_explicit.o configfs_example_macros.o
endif

Thanks,

That just says: if CONFIG_CONFIGFS_FS neq empty_string
  [where the empty_string is between the ",)"]

I think that this patch will do it.  Please let me know if it
does not work.

From: Randy Dunlap <randy.dunlap@oracle.com>

Documentation/ source files that are kernel modules should
not be built when CONFIG_MODULES is not enabled, so change
the Makefile to enforce that.

Thanks for the explanation by disabling CONFIG_CONFIGFS_FS, I get rid
of configfs_example modules. Patch is not required.

Thanks for your help,
