From b0c1dfb82b43b53fb60104f7969b87b7c54cc832 Mon Sep 17 00:00:00 2001 From: Roel Kluin Date: Tue, 13 Dec 2011 10:37:00 +0100 Subject: fuse: fix llseek bug commit b48c6af2086ab2ba8a9c9b6ce9ecb34592ce500c upstream. The test in fuse_file_llseek() "not SEEK_CUR or not SEEK_SET" always evaluates to true. This was introduced in 3.1 by commit 06222e49 (fs: handle SEEK_HOLE/SEEK_DATA properly in all fs's that define their own llseek) and changed the behavior of SEEK_CUR and SEEK_SET to always retrieve the file attributes. This is a performance regression. Fix the test so that it makes sense.
