nfs: fix nfs_size_to_loff_t
See http: //www.infradead.org/rpr.html X-Evolution-Source: 1451162204.2173.11@leira.trondhjem.org Content-Transfer-Encoding: 8bit Mime-Version: 1.0 We support OFFSET_MAX just fine, so don't round down below it. Also switch to using min_t to make the helper more readable. Signed-off-by: Christoph Hellwig <hch@lst.de> Fixes: 433c92379d9c ("NFS: Clean up nfs_size_to_loff_t()") Cc: stable@vger.kernel.org # 2.6.23+ Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
