From b525fcaf0a76507f152d58c6f9e5ef67b3ff552c Mon Sep 17 00:00:00 2001 From: Petr Pavlu Date: Fri, 23 Jan 2026 11:26:57 +0100 Subject: livepatch: Free klp_{object,func}_ext data after initialization The klp_object_ext and klp_func_ext data, which are stored in the __klp_objects and __klp_funcs sections, respectively, are not needed after they are used to create the actual klp_object and klp_func instances. This operation is implemented by the init function in scripts/livepatch/init.c. Prefix the two sections with ".init" so they are freed after the module is initializated.
