I tried to use f_mass_storage to expose a 16TB hard drive attached to Raspberry Pi to another computer.
On the remote computer the recognised drive has incorrect capacity and the data is truncated.

After some debugging I noted the problem is caused by a bug in the read capacity function of f_mass_storage, which had already been fixed upstream in mainline kernel since v5.16

I tried the kernel from https://github.com/raspberrypi/linux version rpi-5.16.y and confirmed that the problem is fixed at v5.16.

I wonder if the fix can be backported to the Ubuntu kernel.

Thank you very much!
