Hi Neil,
In the below patch you changed the error handling, to make the kernel
not setting the size of the device being an error. However we still have
the code in place to handle the error, except it never triggers.
Question is do you remember the reason for this change? Old kernels not
allowing it, are there any legitimate reasons for the kernel to refuse
the size change?
Cheers,
Jes
