Subject: USB: make the autosuspend workqueue thread freezable
To: Greg KH <[EMAIL PROTECTED]>
Cc: USB development list <[email protected]>
Message-ID: <[EMAIL PROTECTED]>
This patch (as881) makes the ksuspend_usb_wq workqueue freezable. We
don't want a rogue workqueue thread running around, unexpectedly
suspending or resuming USB devices in the middle of a system sleep
transition.
