Message-ID: <20060731215933.GB3612@elf.ucw.cz> Date: Mon, 31 Jul 2006 23:59:33 +0200 From: Pavel Machek <pavel@....cz> To: nathans@....com, kernel list <linux-kernel@...r.kernel.org>, "Rafael J. Wysocki" <rjw@...k.pl> Subject: XFS vs. swsusp Hi! Rafael has patches to add bdev freezing to swsusp. I'd like to know if they are neccessary (and why). 1) Is sync() enough to guarantee that all the data written before sync actually reach the platters? (Or is it that data only reach the journal? OTOH that would be okay, too). 2) If we stop all the user proceses and all the kernel threads, is that enough to prevent XFS from writing to disk?
