freeze_processes() (defined in kernel/power/process.c) is called. It executes

try_to_freeze_tasks() that sets TIF_FREEZE for all of the freezable tasks and

either wakes them up, if they are kernel threads, or sends fake signals to them,

to TASK_UNINTERRUPTIBLE and makes it loop until PF_FROZEN is cleared for it.

freeze_processes() (defined in kernel/power/process.c) is called. A system-wide

variable system_freezing_cnt (as opposed to a per-task flag) is used to indicate

whether the system is to undergo a freezing operation. And freeze_processes()
|
||||
sets this variable. After this, it executes try_to_freeze_tasks() that sends a
|
||||
fake signal to all user space processes, and wakes up all the kernel threads.
|
||||
All freezable tasks must react to that by calling try_to_freeze(), which

results in a call to __refrigerator() (defined in kernel/freezer.c), which sets

the task's PF_FROZEN flag, changes its state to TASK_UNINTERRUPTIBLE and makes

__refrigerator() must not be called directly. Instead, use the

they will get a -EPERM error. Thus you can be sure that when
|
||||
usb_kill_urb() returns, the URB is totally idle.
|
||||
|
||||
There is a lifetime issue to consider. An URB may complete at any
|
||||
time, and the completion handler may free the URB. If this happens
|
||||
while usb_unlink_urb or usb_kill_urb is running, it will cause a
|
||||
memory-access violation. The driver is responsible for avoiding this,
|
||||
which often means some sort of lock will be needed to prevent the URB
|
||||
from being deallocated while it is still in use.
|
||||
|
||||
On the other hand, since usb_unlink_urb may end up calling the
|
||||
completion handler, the handler must not take any lock that is held
|
||||
when usb_unlink_urb is invoked. The general solution to this problem
|
||||
is to increment the URB's reference count while holding the lock, then
|
||||
drop the lock and call usb_unlink_urb or usb_kill_urb, and then
|
||||
decrement the URB's reference count. You increment the reference
|
||||
count by calling
|
||||
|
||||
struct urb *usb_get_urb(struct urb *urb)
|
||||
|
||||
(ignore the return value; it is the same as the argument) and
|
||||
decrement the reference count by calling usb_free_urb. Of course,

none of this is necessary if there's no danger of the URB being freed

by the completion handler.
