f2fs: check the use of macros on block counts and addresses
This patch cleans up the existing and new macros for readability.
Rule is like this.
,-----------------------------------------> MAX_BLKADDR -,
| ,------------- TOTAL_BLKS ----------------------------,
| | |
| ,- seg0_blkaddr ,----- sit/nat/ssa/main blkaddress |
block | | (SEG0_BLKADDR) | | | | (e.g., MAIN_BLKADDR) |
address 0..x................ a b c d .............................
| |
global seg# 0...................... m .............................
| | |
| `------- MAIN_SEGS -----------'
`-------------- TOTAL_SEGS ---------------------------'
| |
seg# 0..........xx..................
= Note =
o GET_SEGNO_FROM_SEG0 : blk address -> global segno
o GET_SEGNO : blk address -> segno
o START_BLOCK : segno -> starting block address
