Hi, Its actually impossible to do fsync in such a short time. An option would be to write your NMI routine and after doing fsync call the standard NMI routine. niTin -----Original Message----- From: Julien Danjou <julien@xxxxxxxxxxx> To: Ashwin Ramaswamy <a.galadriel@xxxxxxxxx> Date: Thu, 12 May 2005 14:58:00 +0200 Subject: Re: Ext3 Quick Shutdown On Thu, May 12, 2005 at 06:06:14PM +0530, Ashwin Ramaswamy wrote: > Hi, > I'm working on a 2.4.20-8 kernel running on an ext3 file-system.
