Name:Is this the address of a static object:
Proto:static int static_obj(const void *obj)
Type:int
Parameter:
Type | Parameter | Name |
---|---|---|
const void * | obj |
738 | unsigned long start = (unsigned long) & Usage guidelines:* _text, _data: architecture specific, don't use them in arch-independent code* [_stext, _etext]: contains .text.* sections, may also contain .rodata.** and/or .init.* sections* [_sdata, _edata]: contains , end = (unsigned long) & _end, addr = obj |
742 | If Check if an address is part of freed initmem Then Return 0 |
751 | If arch_is_kernel_data(addr) Then Return 1 |
757 | If is_kernel_percpu_address(addr) Then Return 1 |
763 | Return is_module_address(addr) || is_module_percpu_address(addr) |
Name | Describe |
---|---|
assign_lock_key | Static locks do not have their class-keys yet - for them the key is* the lock object itself. If the lock is in the per cpu area, the* canonical address of the lock (per cpu offset removed) is used. |
lockdep_register_key | Register a dynamically allocated key. |
is_dynamic_key | Check whether a key has been registered as a dynamic key. |
register_lock_class | Register a lock's class in the hash-table, if the class is not present* yet. Otherwise we look it up. We cache the result in the lock object* itself, so actual lookup of the hash should be once per lock object. |
lockdep_init_map | Initialize a lock instance's lock-class mapping info: |
lockdep_unregister_key | Unregister a dynamically allocated key. |
