nilfs2: remove bmap pointer operations
Previously, the bmap codes of nilfs used three types of function tables. The abuse of indirect function calls decreased source readability and suffered many indirect jumps which would confuse branch prediction of processors. This eliminates one type of the function tables, nilfs_bmap_ptr_operations, which was used to dispatch low level pointer operations of the nilfs bmap. This adds a new integer variable "b_ptr_type" to nilfs_bmap struct, and uses the value to select the pointer operations. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
