To: stable@kernel.org Cc: linux-fsdevel@vger.kernel.org, Ext4 Developers List , "Theodore Ts'o" , "Jayson R. King" , "Aneesh Kumar K.V" Message-ID: <1268699165-17461-9-git-send-email-tytso@mit.edu> 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.
