Please do not use attachments when submitting patches.  Please inline
the patch in the body of the mail.  Also please trim extraneous info
when you reply to mails and please do not top-post.

Your patch submissions were not well received by the dm-devel patchwork
(which automatically collects submitted dm-devel patches so they don't
get lost in the shuffle).

Also, please use unique and descriptive subjects for the patches in a
multipatch series.

As for the proposed mpath change: Babu already pointed out that you
don't need this mpath change as the default case already performs

So all you need is that scsi_dh patch to get upstream.  But to do that
you'll need to:
1) create a patch against the upstream scsi-misc tree (not RHEL5.5):

2) send the patch to the linux-scsi vger kernel org mailing list (feel
   free to cc dm-devel too).

Once this change is in the upstream scsi tree it'll propagate to RHEL
