debug_check_no_locks

函数名称：Called when kernel memory is freed (or unmapped), or if a lock* is destroyed or reinitialized - this code checks whether there is* any held lock in the memory range of <from> to <to>:

函数原型：void debug_check_no_locks_freed(const void *mem_from, unsigned long mem_len)

返回类型：void

参数：

类型	参数	名称
const void *	mem_from
unsigned long	mem_len

5278

curr等于当前进程

5283

如果此条件成立可能性小(为编译器优化)(!We want to turn all lock-debugging facilities on/off at once,* via a global flag. The reason is that once a single bug has been* detected and reported, there might be cascade of followup bugs* that would just muddy the log. So we report the first one and)则返回

5286

raw_local_irq_save(flags)

5287

以i小于lockdep_depth 循环

5288

hlock等于held_locks加i

5290

如果not_in_range(mem_from, mem_len, instance, instance的长度)则继续下一循环

5294

print_freed_lock_bug(curr, mem_from, mem_from + mem_len, hlock)

5295

退出

5297

raw_local_irq_restore(flags)
