If anyone has any objections, please let us know. ------------------ From: Aneesh Kumar K.V commit 74baaaaec8b4f22e1ae279f5ecca4ff705b28912 upstream. Ext4 was the only user of range_cont writeback mode and ext4 switched to a different method. So remove the range_cont mode which is not used in the kernel.
