rfh == request for help.
I tried to do $subject and failed miserably.
For how to cause the Documentation/ examples to be built,
I considered using a new CONFIG_ symbol, an environment variable
(or a command-line variable), a completely separate Makefile,
or a "check" string (these are special-cased in the top-level
Makefile). I ended up trying to use a command-line variable "X",
as in:
$ make X=1 all
which sets KBUILD_EX to 1, and then I (tried to) use KBUILD_EX
in top-level and subordinate Makefiles to control building the
example source files.
[For phase 1, I'm only trying to build userspace examples.
Phase 2 can add kernel modules. Then I want to move more examples
out of .txt files into their own example source files as phase 3.]
My patch is below. If anyone can suggest how to make this work,
please let me know. TIA.
