There are some LSM hooks which do not use the common pattern followed by other LSM hooks and thus cannot use call_{int, void}_hook macros and instead use lsm_for_each_hook macro which still results in indirect call. There is one additional generalizable pottern where a hook matching an lsmid is called and the indirect calls for these are addressed with the newly added call_hook_with_lsmid macro which internally uses an implementation similar to call_int_hook but has an additional check that matches the lsmid. For the generic case the lsm_for_each_hook macro is updated to accept a body for the for loop and this handled all cases except getselfattr which also had to provide a prelude to execute before the callback to the LSM.
