Subject: Re: [RFC 0/5] Enable f2fs support inline data

Hi,

This feature is one of my todo items. ;)
Thank you for the contribution.

Before reviewing the below code intensively, we need to check the
following issues.

- deadlock conditions
- FS consistency
- recovery routine

Could you check one more time?
Thanks again,
