Hi,

I second Patrick McLean's e-mail from 2007/02/27.

Patrick also said he was using nfsd at that point.

WARNING: at fs/inotify.c:182 set_dentry_child_flags()
Pid: 19103, comm: gam_server Tainted: P        2.6.24.3-smp #1

 =======================

Running Slackware 2.6.24.3-smp stock kernel. However, ntpdate ran 1 
minute before this occurred (offset 7.4 seconds). Machine was running 
rsync to a remote NFS server (common rsync, not using rsync protocol) 
mounted at the local machine.

Regards,
Cesar

I have this message in the dmesg on a mail server running on an xfs
filesystem. It appears to have happened at some point when nfsd was
restarted, but I can't seem to convince it to reproduce.

The machine is running Gentoo's 2.6.20 kernel.
