[pnfs] [PATCH 2/2] nfs41: Release backchannel resources associated with session

[Ricardo Labiaga]

Benny, 

xprt_destroy_backchannel() lives in
net/sunrpc/xprt_destroy_backchannel.c which has not yet been pushed to
the nfs41 branch.  You may want to apply this patch to the
rlabiaga-bc-response-v1 branch instead.
