From 57c104f15a781e0239e1fe6af3aa0206866fc34e Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 8 Feb 2016 21:11:50 +0100 Subject: [PATCH] nfs: fix nfs_size_to_loff_t [ Upstream commit 50ab8ec74a153eb30db26529088bc57dd700b24c ] 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.
