From 5cf32524de745c56e1411d63eccf23fef1709d73 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Tue, 31 Mar 2009 16:06:27 +0100 Subject: [PATCH] GFS2: Fix symlink creation race In certain cases symlinks can appear to have zero size if a lookup on the inode occurs within a certain (very short) time after the symlink has been created. The symlink is correctly created on disk but appears to have zero size when stat()ed. This patch closes the race and prevents incorrect sizes appearing.
