Hi folks,
make randconfig seems to allow chosing more than one slab allocator
although they are all part of a choice,endchoice block (and none are
tristate). The following quickly finds both CONFIG_SLUB and CONFIG_SLOB
enabled:
$ while [ 1 ]; do make randconfig &> /dev/null; if [ $(grep "CONFIG_SL[OU]B=y" .config | wc -l) == 2 ]; then break; fi; done
$ grep CONFIG_SL[OU]B=y .config
CONFIG_SLUB=y
CONFIG_SLOB=y
whereas if I do this:
diff --git a/scripts/kconfig/confdata.c b/scripts/kconfig/confdata.c
--- a/scripts/kconfig/confdata.c
+++ b/scripts/kconfig/confdata.c
@@ -1063,7 +1063,7 @@ static void randomize_choice_values(struct symbol *csym)
expr_list_for_each_sym(prop->expr, e, sym) {
if (def == cnt++) {
sym->def[S_DEF_USER].tri = yes;
- csym->def[S_DEF_USER].val = sym;
+// csym->def[S_DEF_USER].val = sym;
}
else {
sym->def[S_DEF_USER].tri = no;
then it never happens and the "while [ 1 ]; done" loop above never
returns.
I haven't investigated it yet, but thought I'd bring it up because it
often creates invalid configs.
Thanks.
