1This file explains the locking and exclusion scheme used in the PCCARD
2and PCMCIA subsystems.

4
5A) Overview, Locking Hierarchy:
6===============================
7
8pcmcia_socket_list_rwsem - protects only the list of sockets
9- skt_mutex - serializes card insert / ejection
10 - ops_mutex - serializes socket operation
11
12
13B) Exclusion
14============
15
16The following functions and callbacks to struct pcmcia_socket must
17be called with "skt_mutex" held:
18
19 socket_detect_change()
20 send_event()
21 socket_reset()
22 socket_shutdown()
23 socket_setup()
24 socket_remove()
25 socket_insert()
26 socket_early_resume()
27 socket_late_resume()
28 socket_resume()
29 socket_suspend()
30
31 struct pcmcia_callback *callback
32
33The following functions and callbacks to struct pcmcia_socket must
34be called with "ops_mutex" held:
35
36 socket_reset()
37 socket_setup()
38
39 struct pccard_operations *ops
40 struct pccard_resource_ops *resource_ops;
41
42Note that send_event() and struct pcmcia_callback *callback must not be
43called with "ops_mutex" held.

963. Per PCMCIA-device Data:
97--------------------------
98
99The "main" struct pcmcia_devie is protected as follows (read-only fields
100or single-use fields not mentioned):
