Subject: [PATCH] nfs-utils: rpc.mountd: cache debugging statements
Date: Tue, 02 Oct 2007 10:22:10 -0400	[thread overview]
Message-ID: <47025412.5010603@RedHat.com> (raw)

The following patch adds some debugging statement to rpc.mound
that show what data is being passed up from the kernel during
mounts. I found these to be very useful but non obtrusive
in my recent travels...

This patch is relative to the Fedora nfs-utils git tree:
git://git.infradead.org/~steved/nfs-utils.fedora

but does apply to Neil's git tree.

commit 6e7d2cd031bd019c71db2c70851bcc5709105c1d
Author: Steve Dickson <steved@dickson.boston.devel.redhat.com>
Date:   Tue Oct 2 09:03:55 2007 -0400

     Added a couple debugging statements to the caching
     code that shows data be sent up from the kernel.
     These statements were very using in debugging some
     recent issues.
