From stern@rowland.harvard.edu Mon Nov 26 22:50:47 2007 From: Alan Stern Date: Mon, 19 Nov 2007 10:15:02 -0500 (EST) Subject: USB: make ksuspend_usbd thread non-freezable To: Greg KH Cc: USB development list Message-ID: This patch (as1012b) makes the ksuspend_usbd kernel thread non-freezable. Since the PM core has been changed to lock all devices during a system sleep, the thread no longer needs to be frozen. It won't interfere with a system sleep because before trying to resume a root hub device, it acquires the device's lock.
