Darrick J. Wong 1ec9307fc0 xfs: allow unlinked symlinks and dirs with zero size ... For a very very long time, inode inactivation has set the inode size to zero before unmapping the extents associated with the data fork. Unfortunately, commit 3c6f46eacd changed the inode verifier to prohibit zero-length symlinks and directories. If an inode happens to get logged in this state and the system crashes before freeing the inode, log recovery will also fail on the broken inode. Therefore, allow zero-size symlinks and directories as long as the link count is zero; nobody will be able to open these files by handle so there isn't any risk of data exposure.
