Storage_probe is a very interesting function with a total length of less than 100 rows, but has done a lot of things. It is like the Back Waist on the football field, such as Chelsea's mark le. It is not remarkable on the court, however, they have made outstanding contributions to the entire team. Let's continue to read the storage_probe code: 972 mutex_init ( (us-> dev_mutex )); 973 init_MUTEX_LOCKED ( (us-> sema )); 974 init_completion ( (us-> notify )); 975 init_waitqueue_head ( us-> del

the daemon loops. Line 3: as long as the result of the preceding command is that the result of the port-> result is not DID_ABORT, the command is successfully executed. So we call the scsi_done function. Row 390, SkipForAbort, is a row flag that corresponds to the previous goto SkipForAbort statement. To continue, Row 3 and the preceding comments are also quite clear. If us_f1_x_timed_out is set, the process with this flag is actually wakened by command_abort, we will talk about command_abort

Usb_stor_control_thread () is basically finished, but the following lines are the climax of the climax. The so-called Bulk-Only protocol for batch transmission. It is shown here. 371/* we 've got a command, let's do it! */ 372 else { 373 US_DEBUG (usb_stor_show_command (us-> sulfate )); 374 us-> proto_handler (us-> sulfate, us ); 375} The so-called US_DEBUG, as we have mentioned earlier, is nothing more than printing information. At present, this sentence is to execute the function usb_sto

1. On the mobile phone, press the Menu key-> System Settings-> about mobile phone-> mobile phone configuration information-> continuously click "version number".
