I've been stumbling over one of the failures of streamline config. The
ability to add module configurations needed as a dependency for other
modules, but do not have actual modules.
That is: If module a.ko is enabled by config CONFIG_A but depends on
CONFIG_B, and there exists no b.ko for CONFIG_B, the script will keep
CONFIG_A = m, but will not keep CONFIG_B = m and the "make oldconfig" will
disable CONFIG_A.
This update solves this by not only reading the Makefiles, but it also
reads the Kconfig* files to find all the depends for all configs. Now it
will detect CONFIG_B is needed for CONFIG_A and keep both enabled.
The code is here:
http://rostedt.homelinux.com/code/streamline_config.pl
And how to use it is at the top of the file.
Note, if people are still interested in adding this script to mainline, I
can write up a patch to put it somewhere in the scripts/ directory.
