selinux and readahead

Dear all, 

I have encountered the following setroubleshoot warning:


Summary:

SELinux is preventing readahead (readahead_t) "read" to inotify (inotifyfs_t).

Detailed Description:

SELinux denied access requested by readahead. It is not expected that this
access is required by readahead and this access may signal an intrusion attempt.
It is also possible that the specific version or configuration of the
application is causing it to require additional access.

Allowing Access:

Sometimes labeling problems can cause SELinux denials. You could try to restore
the default system file context for inotify,

restorecon -v 'inotify'

If this does not work, there is currently no automatic way to allow this access.
Instead, you can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.

I do not know if readahead should be denied or not?  What do you recommend that I do?
