Same, on vanilla kernel with randseed disabled.

Problem is reproductible for me on vanilla kernel with randstruct disabled, if it needs to be sent upstream.

At this moment, I switched from f2fs and unable to reproduce the problem.

Ok, are you planning on switching back or are you done with f2fs ?
