From 77e03677ac76d413fbb6d6caaffa1d64877a0c2a Mon Sep 17 00:00:00 2001 From: Benny Halevy Date: Tue, 24 Jun 2008 20:25:57 +0300 Subject: [PATCH] nfs: initialize timeout variable in nfs4_proc_setclientid_confirm MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit gcc (4.3.0) rightfully warns about this: /usr0/export/dev/bhalevy/git/linux-pnfs-bh-nfs41/fs/nfs/nfs4proc.c: In function ‘nfs4_proc_setclientid_confirm’: /usr0/export/dev/bhalevy/git/linux-pnfs-bh-nfs41/fs/nfs/nfs4proc.c:2936: warning: ‘timeout’ may be used uninitialized in this function nfs4_delay that's passed a pointer to 'timeout' is looking at its value and sets it up to some value in the range: NFS4_POLL_RETRY_MIN..NFS4_POLL_RETRY_MAX if (*timeout <= 0) *timeout = NFS4_POLL_RETRY_MIN; if (*timeout > NFS4_POLL_RETRY_MAX) *timeout = NFS4_POLL_RETRY_MAX; Therefore it will end up set to some sane, though rather indeterministic, value.
