* LOCKING RULES
|
|
* =============
|
|
*
|
|
* This channel driver uses several locks. One must be
|
|
* careful not to reverse the locking order, which will
|
|
* lead to a so called deadlock. Here is the locking order
|
|
* that must be followed:
|
|
*
|
|
* struct capi_pvt *i;
|
|
*
|
|
* 1. cc_mutex_lock(&i->owner->lock); **
|
|
*
|
|
* 2. cc_mutex_lock(&i->lock);
|
|
*
|
|
* 3. cc_mutex_lock(&iflock);
|
|
* 4. cc_mutex_lock(&messagenumber_lock);
|
|
* 5. cc_mutex_lock(&usecnt_lock);
|
|
* 6. cc_mutex_lock(&capi_put_lock);
|
|
*
|
|
*
|
|
* ** the PBX will call the callback functions with
|
|
* this lock locked. This lock protects the
|
|
* structure pointed to by 'i->owner'. Also note
|
|
* that calling some PBX functions will lock
|
|
* this lock!
