Hi Jaegeuk,
Can we split in place update bios into single sbi->f2fs_bio_info for more page
merged in out place update? This case can be show as below:
in place update submit a bio with one page
out place update submit a bio with one page
in place update submit a bio with one page
Hi Jaegeuk,
I try this patch and find it can fix below case:
kworker/u16:3-423 [002] 183.812347: submit_bio: kworker/u16:3(423):
WRITE block 104749352 on mmcblk0p50 (8 sectors)
fio-2122 [003] 183.812380: submit_bio: fio(2122): WRITE
block 104749360 on mmcblk0p5

It would better split small and large IOs separately in order to get more
consecutive big writes.
The default threshold is set to 64KB, but configurable by sysfs/min_hot_blocks.
