mkfs.f2fs: refactor format flow for cleanup
During formatting device, node/data block and filesystem metatdata related
to same inode were updated in separated functions, e.g. for root inode:
- f2fs_write_root_inode() updates root inode's block
- f2fs_write_check_point_pack updates its nat/sit journal, summary block
Result in:
- there are some redundant codes in between f2fs_write_check_point_pack()
and functions in f2fs_create_root_dir().
- readability is bad due to filesystem meta and data/node updates in
separated places.
- bad scalability if we want to add more default inode.
So that, this patch introduces below functions:
- update_sit_journal
- update_nat_jounral
- update_summary_entry
Then use them to update inode related metadata into cache in below
functions:
- f2fs_write_root_inode
- f2fs_add_default_dentry_root
- f2fs_write_qf_inode
- f2fs_write_default_quota
- f2fs_write_lpf_inode
- f2fs_write_lpf_inode
Finally, f2fs_write_check_point_pack() can write back cached metadata
into CP area directly.
