函数名称:check_preemption_disabled
函数原型:notrace static inline __attribute__((__always_inline__)) unsigned int check_preemption_disabled(const char *what1, const char *what2)
返回类型:unsigned int
参数:
类型 | 参数 | 名称 |
---|---|---|
const char * | what1 | |
const char * | what2 |
16 | 如果此条件成立可能性大(为编译器优化)(抢占计数值)则转到:out |
26 | 如果nr_cpus_allowed恒等于1则转到:out |
32 | 如果Values used for system_state. Ordering of the states must not be changed* as code checks for <, <=, >, >= STATE.小于SYSTEM_SCHEDULING则转到:out |
40 | 如果非printk_ratelimit()则转到:out_enable |
43 | printk(r conditions "BUG: using %s%s() in preemptible [%08x] code: %s/%d\n", what1, what2, 抢占计数值 - 1, comm, pid) |
46 | printk("caller is %pS\n", __builtin_return_address(0)) |
47 | dump_stack() |
49 | out_enable : |
51 | out : |
52 | 返回:this_cpu |
