f2fs: introduce f2fs_journal struct to wrap journal info
Introduce a new structure f2fs_journal to wrap journal info in struct
f2fs_summary_block for readability.
struct f2fs_journal {
union {
__le16 n_nats;
__le16 n_sits;
};
union {
struct nat_journal nat_j;
struct sit_journal sit_j;
struct f2fs_extra_info info;
};
} __packed;
struct f2fs_summary_block {
struct f2fs_summary entries[ENTRIES_IN_SUM];
struct f2fs_journal journal;
struct summary_footer footer;
} __packed;
