[f2fs-dev] [PATCH] f2fs: improve print log in f2fs_sanity_check_ckpt()

[Chao Yu]

As Park Ju Hyung suggested:

"I'd like to suggest to write down an actual version of f2fs-tools
here as we've seen older versions of fsck doing even more damage
and the users might not have the latest f2fs-tools installed."

This patch give a more detailed info of how we fix such corruption
to user to avoid damageable repair with low version fsck.

How about adding the patch name as well?

For end-user, I think they don't care about commit id or patch title...

But anyway, let me send v2 as you suggested, either one is okay to me.

Thanks,
