Please pull bdc54d8e3cb4 to 4.7

[Jason L Tibbitts III <tibbs@math.uh.edu>]

Please consider pulling bdc54d8e3cb4 into the 4.7 series.  (And 4.6 if
it's still going.)  This patch is in v4.8-rc1:

Subject: [PATCH] SUNRPC: Fix infinite looping in rpc_clnt_iterate_for_each_xprt

After over a week of debugging, I found 80b14d5e61ca (which went in
during the 4.6 merge window) be the cause of a particularly bad NFS
client issue which was killing my servers
(https://bugzilla.redhat.com/show_bug.cgi?id=1369600).  The client issue
seems to be fixed by bdc54d8e3cb4; I've patched that into 4.7.2 on about
150 NFS client desktops and the problem has gone away without
introducing any regressions that I can see.

I do not know why this was not initially submitted to stable; I asked
Trond if he would submit it and he suggested that I do so instead.

Thanks,
