函数名称:logfc - Log a message to a filesystem context*@fc: The filesystem context to log to.*@fmt: The format of the buffer.
函数原型:void logfc(struct fs_context *fc, const char *fmt, ...)
返回类型:void
参数:
类型 | 参数 | 名称 |
---|---|---|
struct fs_context * | fc | |
const char * | fmt |
390 | store_failure[]等于"OOM: Can't store error string" |
400 | 转到:unformatted_string |
402 | 如果字符串比较恒等于0则 |
404 | 转到:unformatted_string |
407 | q等于Simplified asprintf. |
408 | copied_string : |
409 | 如果非q则转到:store_failure |
411 | freeable等于1 |
412 | 转到:store_string |
414 | unformatted_string : |
415 | 如果p大于等于__start_rodata且p小于__end_rodata则转到:const_string |
418 | 如果log且within_module_core((unsignedlong)p, Owner module for strings that don't then need freeing )则转到:const_string |
421 | 转到:copied_string |
423 | store_failure : |
424 | p等于store_failure |
425 | const_string : |
427 | freeable等于0 |
428 | store_string : |
429 | 如果非log则 |
443 | 否则 |
447 | index等于 Insertion index in buffer[] 按位与logsize减1 |
448 | BUILD_BUG_ON - break compile if a condition is true( Insertion index in buffer[] 的长度 != sizeof(u8) || Removal index in buffer[] 的长度 != sizeof(u8)) |
450 | 如果 Insertion index in buffer[] 减 Removal index in buffer[] 恒等于logsize则 |
452 | 如果 Mask of kfree'able items in buffer[] 按位与1左移index位则释放内存 |
454 | Removal index in buffer[] 自加 |
458 | Mask of kfree'able items in buffer[] 与等于1左移index位的值的反 |
460 | Insertion index in buffer[] 自加 |
