nilfs2: disk address translator This adds the disk address translation file (DAT) whose primary function is to convert virtual disk block numbers to actual disk block numbers. The virtual block numbers of NILFS are associated with checkpoint generation numbers, and this file also provides functions to manage the lifetime information of each virtual block number.

nilfs2: clean up old e-mail addresses E-mail addresses of osrg.net domain are no longer available. This removes them from authorship notices and prevents reporters from being confused.

nilfs2: move ioctl interface and disk layout to uapi separately The header file "include/linux/nilfs2_fs.h" is composed of parts for ioctl and disk format, and both are intended to be shared with user space programs. This moves them to the uapi directory "include/uapi/linux" splitting the file to "nilfs2_api.h" and "nilfs2_ondisk.h". The following minor changes are accompanied by this migration: - nilfs_direct_node struct in nilfs2/direct.h is converged to nilfs2_ondisk.h because it's an on-disk structure. - inline functions nilfs_rec_len_from_disk() and nilfs_rec_len_to_disk() are moved to nilfs2/dir.c.

nilfs2: add update functions of virtual block address to dat This is a preparation for the successive cleanup ("nilfs2: allow btree to directly call dat operations"). This adds functions bundling a few operations to change an entry of virtual block address on the dat file. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

nilfs2: separate constructor of metadata files This will displace nilfs_mdt_new() constructor with individual metadata file constructors like nilfs_dat_new(), new_sufile_new(), nilfs_cpfile_new(), and nilfs_ifile_new(). This makes it possible for each metadata file to have own intialization code. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
