f2fs: refactor bio->rw handling
This patch introduces f2fs_io_info to mitigate the complex parameter list. struct f2fs_io_info { enum page_type type; /* contains DATA/NODE/META/META_FLUSH */ int rw; /* contains R/RS/W/WS */ int rw_flag; /* contains REQ_META/REQ_PRIO */ } 1. f2fs_write_data_pages - DATA - WRITE_SYNC is set when wbc->WB_SYNC_ALL. 2. sync_node_pages - NODE - WRITE_SYNC all the time 3. sync_meta_pages - META - WRITE_SYNC all the time - REQ_META | REQ_PRIO all the time ** f2fs_submit_merged_bio() handles META_FLUSH. 4. ra_nat_pages, ra_sit_pages, ra_sum_pages - META - READ_SYNC Cc: Fan Li <fanofcode.li@samsung.com> Cc: Changman Lee <cm224.lee@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk.kim@samsung.com>
