[PATCH 03/24] btrfs: add setlease file operation

[Jeff Layton]

Add the setlease file_operation to btrfs_file_operations and
btrfs_dir_file_operations, pointing to generic_setlease.  A future
patch will change the default behavior to reject lease attempts with
-EINVAL when there is no setlease file operation defined. Add
generic_setlease to retain the ability to set leases on this
filesystem.
