Subject: [PATCH] nfs41: get rid of unused struct nfs41_exchange_id_res members
From: Benny Halevy <bhalevy () panasas ! com>
Date: 2009-05-01 20:14:46
Message-ID: 1241208886-5748-1-git-send-email-bhalevy () panasas ! com
[Download RAW message or body]
struct nfs41_exchange_id_res is currently allocated on the stack
insanely taking over 2K of stack space due to the NFS4_OPAQUE_LIMIT (1K(
byte arrays embedded in server_owner and server_scope.
Since these are not in use yet, this patch gets rid of them for the
time being.
