Thank you for your patch.

Unfortunately it does not apply to my 4.1.15 or newer 4.1.y sources,
and I do not have the knowledge of f2fs internals to modify your
patch myself. E.g. 4.1.y lacks the '.journal' field in the
'struct curseg_info'.

Could you make a version suitable for 4.1.y ?

Best regards

Philippe
