Subject: swsusp: Vojtech pointed error in usb/hub.c
Date: Thu, 1 Aug 2002 12:39:58 +0200 [thread overview]
Message-ID: <20020801103957.GA128@elf.ucw.cz> (raw)
Hi!
We do not want threads exiting because of suspend, so refrigerator
should be just before test for signals pending (so it has chance to
kill them).
