| |
2.6.27-stable review patch. If anyone has any objections, please let us know.
------------------
From: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
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.
