Issue

A NFS client DI issue and patch was described on the linux NFS list
In reviewing the code in xprtsock.c and using systemtap on xs_tcp_send_request it would appear the Red Hat 6.x kernels would be exposed to this issue.
- Can the Red Hat NFS team provide input on this issue?
- Can Red Hat confirm that this appears to be a valid exposure in the Red Hat RHEL 6.x kernel. If so, does the patch provided on the email list appear to be a valid method to address the issue?

Environment

Red Hat Enterprise Linux 6.4
kernel-2.6.32-358
