函数名称:apply_jump_label_nops - patch module jump labels with arch_get_jump_label_nop()*@mod: module to patch* Allow for run-time selection of the optimal nops. Before the module* loads patch these with arch_get_jump_label_nop(), which is specified by

函数原型:void jump_label_apply_nops(struct module *mod)

返回类型:void

参数:

类型参数名称
struct module *mod
592  iter_start等于jump_entries
593  iter_stop等于iter_startnum_jump_entries
597  如果iter_start恒等于iter_stop则返回
600 iter小于iter_stop循环
602  如果jump_label_init_type(iter)恒等于JUMP_LABEL_NOPUpdate code which is definitely not currently executing.* Architectures which need heavyweight synchronization to modify* running code can override this to make the non-live update case* cheaper.
