From b8356c465b42c162f34b5fd4102a6c27cec36f43 Mon Sep 17 00:00:00 2001 From: Valerie Clement Date: Tue, 5 Feb 2008 10:56:37 -0500 Subject: ext4: Don't set EXTENTS_FL flag for fast symlinks For fast symbolic links, the file content is stored in the i_block[] array, which is not compatible with the new file extents format. e2fsck reports error on such files because EXTENTS_FL is set. Don't set the EXTENTS_FL flag when creating fast symlinks. In the case of file migration, skip fast symbolic links.
