Please break this down in logical change!
There is very good stuff in this patch but it need to be digested slowly :)
I'd see it as:
- introduce the config structure
- convert all globals reference to use structure members
- get rid of these `_level' prefix and NULL pointer passing.
- then introduce the subsource logic (and please separate parser
update and regen of shipped file)
There is no need for the `_level' prefixing, NULL pointer passing, and
conditionally select the structure or the global. The sub-tree should
be treated the same way as the global tree. Basically:
- if (!sym_defconfig_list) {
+ if (!(l ? l->sym_defconfig_list : sym_defconfig_list)) {
should just be:
- if (!sym_defconfig_list) {
+ if (!l->sym_defconfig_list) {
no extra complexity/un-maintainability. You may not even need to
change function prototypes if the current tree never expect to use
anything but `current_config'.
On a performance p.o.v., you may want to have one commit caching the
prefix length, to avoid all the strlen(...).
on a pure stylistic side
- don't pass 0 when you mean NULL (well, you will no longer need that actually)
- loop with 6 level of indentation are hideous, especially for
condition where you can just `break;' early
I'll prepare a new patch next week with your suggestion. Its
nice to hear that there is some interest in this.
