btrfs: rename btrfs_leaf_data to BTRFS_LEAF_DATA_OFFSET
Commit 5f39d397dfbe ("Btrfs: Create extent_buffer interface for large blocksizes") refactored btrfs_leaf_data function to take extent_buffer rather than struct btrfs_leaf. However, as it turns out the parameter being passed is never used. Furthermore this function no longer returns the leaf data but rather the offset to it. So rename the function to BTRFS_LEAF_DATA_OFFSET to make it consistent with other BTRFS_LEAF_* helpers and turn it into a macro. Signed-off-by: Nikolay Borisov <nborisov@suse.com> [ removed () from the macro ] Signed-off-by: David Sterba <dsterba@suse.com>
