Hi all,
Could we move IPU judgement outside cp_rwsem lock like below:
if (set ipu policy)
if (ipu success)
return
lock_op
opu

And at same time when we write new checkpoint, we set ipu policy
during whole cp, the process is like this:

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

Hi Jaegeuk,
I try this patch and find it can fix below case:

Hi all,
I am really confused by the condition below use sec_freed, is it always equal

Or, gc more process will recheck this condition?
