Btrfs: Add mount option to turn off data cow A number of workloads do not require copy on write data or checksumming. mount -o nodatasum to disable checksums and -o nodatacow to disable both copy on write and checksumming. In nodatacow mode, copy on write is still performed when a given extent is under snapshot. Signed-off-by: Chris Mason <chris.mason@oracle.com>
