Subject: swsusp: fix process start times after resume
Date: Mon, 4 Oct 2004 14:10:18 +0200 [thread overview]
Message-ID: <20041004121018.GA25734@elf.ucw.cz> (raw)
Hi!
Currently, process start times change after swsusp (because they are
derived from jiffies and current time, oops). This should fix
it. Please apply,
Pavel
