# backport Kconfig
#
# Some options are user-selectable ("BPAUTO_USERSEL_*")
#
# Most options, however, follow a few different schemes:
#
# A) An option that is selected by drivers ("select FOO") will be
# changed to "select BPAUTO_FOO" (if the option BPAUTO_FOO
# exists). The option BPAUTO_FOO then controls setting of the
# BPAUTO_BUILD_FOO option, which is a module, like this:
#
# config BPAUTO_BUILD_FOO
# tristate
# # or bool
#
# # not possible on kernel < X.Y, build will fail if any
# # drivers are allowed to build on kernels < X.Y
# depends on KERNEL_X_Y
#
# # don't build the backport code if FOO is in the kernel
# # already, but only if the kernel version is also >= X.Z;
# # this is an example of backporting where the version of
# # the FOO subsystem that we need is only available from
# # kernel version X.Z
# depends on !FOO || KERNEL_X_Z
#
# # build if driver needs it (it selects BPAUTO_FOO)
# default m if BPAUTO_FOO
#
# # or for build-testing (BPAUTO_USERSEL_BUILD_ALL is enabled)
# default m if BPAUTO_USERSEL_BUILD_ALL
#
# config BPAUTO_FOO
# bool
#
# This only works as-is if the kernel code is usable on any version,
# otherwise the "&& !FOO" part needs to be different.
#
#
# B) An option for code always present on some kernels (e.g. KFIFO).
# This simply depends on/sets the default based on the version:
#
# config BPAUTO_BUILD_KFIFO
# def_bool y
# depends on KERNEL_2_6_36
#
#
# C) similarly, a kconfig symbol for an option, e.g.
# BPAUTO_OPTION_SOME_FIX (no examples provided) check git log
#
#
# Variations are obviously possible.
#
config BP_MODULES

bool
default MODULES
help
This symbol is necessary for the newer kconf tool, it looks
for the "option modules" to control the 'm' state.

This option selects all the compat code options
that would otherwise only be selected by drivers.
It's only really useful for compat testing, so
you probably shouldn't enable it.
