2008-02-10ext4: Fix circular locking dependency with migrate and rm.Aneesh Kumar K.V
In order to prevent a circular locking dependency when an unlink operation is racing with an ext4 migration, we delay taking i_data_sem until just before switch the inode format, and use i_mutex to prevent writes and truncates during the first part of the migration operation.

2008-02-05ext4: Don't set EXTENTS_FL flag for fast symlinksValerie Clement
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.
