[xiezhanyan]

Is there a solution about this, thanks

[pankaj1jul]

We have fixed this. Just merging the changes. Please use the latest one.

I will ask Developers to make it available for all the possible Kernel Version with the support matrix. Thanks for reaching out to us.

by the way, android(aosp) use fuse fs for sdcard partition. wrapfs vs fusefs, it improve io speed.
i think you guys can merge wrapfs into aosp, it will help a lot.
