函数名称：Initialize debugfs for the locking event counts.

函数原型：static int __init init_lockevent_counts(void)

返回类型：int

参数：无

146  d_counts等于debugfs_create_dir(LOCK_EVENTS_DIR, NULL)
149  如果非d_counts则转到:out
159  以i小于 # of write lock handoffs 循环
160  如果skip_lockevent(When CONFIG_LOCK_EVENT_COUNTS is enabled, event counts of different* types of locks will be reported under the /lock_event_counts/* directory. See lock_events_list.h for the list of available locking* events.* Writing to the special "[i])则继续下一循环
162  如果非debugfs_create_file(When CONFIG_LOCK_EVENT_COUNTS is enabled, event counts of different* types of locks will be reported under the /lock_event_counts/* directory. See lock_events_list.h for the list of available locking* events.* Writing to the special "[i], 0400, d_counts, (void * )(long)i, & Debugfs data structures)则转到:fail_undo
167  如果非debugfs_create_file(When CONFIG_LOCK_EVENT_COUNTS is enabled, event counts of different* types of locks will be reported under the /lock_event_counts/* directory. See lock_events_list.h for the list of available locking* events.* Writing to the special "[LOCKEVENT_reset_cnts], 0200, d_counts, (void * )(long)LOCKEVENT_reset_cnts, & Debugfs data structures)则转到:fail_undo
172  返回:0
173  fail_undo :
174  debugfs_remove_recursive(d_counts)
175  out :
176  打印警告信息("Could not create '%s' debugfs entries\n", LOCK_EVENTS_DIR)
177  返回:负ENOMEM
