I have not looked in this more accurately (yet). - -locking: -locking is done by means of three structures. -1- ieee->lock (by means of spin_[un]lock_irq[save/restore] -2- ieee->wx_sem -3- ieee->scan_sem - -the lock 1 is what protect most of the critical sections in the ieee stack. -the lock 2 is used to avoid that more than one of the SET wireless extension -handlers (as well as start/stop protocol function) are running at the same time. -the lock 1 is used when we need to modify or read the shared data in the wx handlers. -In other words the lock 2 will prevent one SET action will run across another SET -action (by make sleep the 2nd one) but allow GET actions, while the lock 1 -make atomic those little shared data access in both GET and SET operation. -So get operation will be never be delayed really: they will never sleep.. -Furthermore in the top of some SET operations a flag is set before acquiring -the lock. This is an help to make the previous running SET operation to -finish faster if needed (just in case the second one will totally undo the -first, so there is not need to complete the 1st really.. ). -The background scanning mechaninsm is protected by the lock 1 except for the -workqueue. this wq is here just to let the set_chan callback sleep (I thinked it -might be appreciated by USB network card driver developer). In this case the lock 3 -take its turn. -Thus the stop function needs both the locks. -Funny in the syncro scan the lock 2 play its role (as both the syncro_scan -function and the stop scan function are called with this semaphore held). - - diff --git a/drivers/staging/rtl8192su/ieee80211/rtl819x_BA.h b/drivers/staging/rtl8192su/ieee80211/rtl819x_BA.h deleted file mode 100644 index 1c2a40b75a19..000000000000 --- a/drivers/staging/rtl8192su/ieee80211/rtl819x_BA.h +++ /dev/null @@ -1,79 +0,0 @@ -/****************************************************************************** - * Copyright(c) 2008 - 2010 Realtek Corporation.
