[PATCH 001 of 4] knfsd: Allow nfsd READDIR to return 64bit cookies

From: NeilBrown
Date: Thu Mar 22 2007 - 20:47:29 EST



->readdir passes lofft_t offsets (used as nfs cookies) to
nfs3svc_encode_entry{,_plus}, but when they pass it on to
encode_entry it becomes an 'off_t', which isn't good.

So filesystems that returned 64bit offsets would lose.
