The f2fs has three bio types, NODE, DATA, and META, and manages some data
structures per each bio types.
The codes are a little bit messy, thus, this patch introduces a bio array
which groups individual data structures as follows.
struct f2fs_bio_info {
struct bio *bio; /* bios to merge */
sector_t last_block_in_bio; /* last block number */
struct mutex io_mutex; /* mutex for bio */
};
struct f2fs_sb_info {
...
struct f2fs_bio_info write_io[NR_PAGE_TYPE]; /* for write bios */
...
};
The code changes from this new data structure are trivial.
