Re: f2fs causes system stall

[Jaegeuk Kim]

Hi,

Thank you for the report.
When I veiwed the patch at a glance, it seems that reverting is not a
good way.

Instead, could you share the f2fs commit point that you're using?
Then, since I have a suspect for this issue, I'd like to write a patch
to test.

Thanks,
