 I had a brief look at configuring pnfs recently and wondered why 


suggested that the layout module should be explicitly 'modprobe'd when that
sort of thing is normally automatic.
pnfs.c makes the appropriate 'request-module' call, but there is no
MODULE_ALIAS to link the relevant module with the requested name.

This patch adds the required MODULE_ALIAS.  It has only been compile-tested
(my interest is as yet only theoretical :-)

Subject: [PATCH] Declare modalias for nfs4filelayout to support auto-loading of modules.

pnfs.c uses 'request_module' with the name

when it actually wants

so give the latter a "MODULE_ALIAS" so it can be found with the former

This avoids needing to add an alais to /etc/modprobe.d/...
