From f73f284b235daec5e2059d778c7c8ef5a8f4f3b0 Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Fri, 27 Jan 2012 13:05:07 -0600 Subject: [PATCH] 278: Ensure lost+found is not created with wrong link count xfs_repair was leaving lost+found directory with a wrong link count when a cleaned inode was re-used to create lost+found. This test case confirm that, after xfs_repair is executed, the lost+found inode is left in a consistent state.
