[pnfs] [PATCH 0/3] layout_return and return_on_close

[Benny Halevy]

Following are three patches to fix layout_return wire format and use of 
return_type (vs. layout_type), a rather cosmetic change (but important 
IMHO) to add an enumerated type for pnfs iomode, and finally implement
return_on_close.
