From: NeilBrown Date: Tue, 27 Mar 2007 05:32:08 +0000 (-0800) Subject: [PATCH] knfsd: allow nfsd READDIR to return 64bit cookies X-Git-Tag: accepted/tizen/common/20141203.182822~32357 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=598b9a56373f0596ed48f7af730706aaee998d5f;p=platform%2Fkernel%2Flinux-arm64.git [PATCH] knfsd: allow nfsd READDIR to return 64bit cookies ->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.
