[f2fs-dev] [PATCH] f2fs: use new ioprio Macro to get ckpt thread ioprio data

[Zhiguo Niu]

Use new Macro IOPRIO_PRIO_LEVEL to get ckpt thread ioprio data(level),
it is more accurate and consisten with the way setting ckpt thread
ioprio(IOPRIO_PRIO_VALUE(class, data)).

So, can you please use 'level' to instead 'data' in f2fs_sbi_show() and
__sbi_store()?

Hi Chao,

IOPRIO_PRIO_DATA in the new kernel version includes two parts: level and hint.
In __sbi_store, " IOPRIO_PRIO_VALUE(class, data)"  is used to set ckpt
iopriority,
and it will pass default hint value, we just need to keep class /level right.

 #define IOPRIO_PRIO_VALUE(prioclass, priolevel) \
   ioprio_value(prioclass, priolevel, IOPRIO_HINT_NONE)
so i think this part is not needed to modify.

thanks!

Zhiguo,

I think f2fs only support configuring priolevel rather than priolevel and
priohint of ckpt thread via ckpt_thread_ioprio sysfs interface, so it will
be more readable to use 'level' instead of 'data' in context of the interface,
thoughts?

Thanks,

Hi  Chao,
I understand what you said and I agree with this. I will update it in
the next version.
