I have an issue where parent->variantType is being set to YAFFS_OBJECT_TYPE_DIRECTORY but the variant.directoryVariant.children.next is never set so it ends up crashing at ------------------------------------------------------------------ /* Now add it */ list_add(&obj->siblings, &directory->variant.directoryVariant.children); ------------------------------------------------------------------ inside yaffs_AddObjectToDirectory() The variantType is being set to YAFFS_OBJECT_TYPE_DIRECTORY here: ------------------------------------------------------------------ /* we need to load this info */ in->valid = 1; in->variantType = oh->type; ------------------------------------------------------------------ Thanks very much for any guidance.
