Re: linux-next: build failure after merge of the vfio tree

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Thank you. The errors indicate that, most likely, the fsl-mc-bus patches from char-misc-next are missing at this point. I have added the vfio patches on top of linux-next (which already contains the fsl-mc-bus patches) and built x86_64 allmodconfig. There were no errors.

Thanks,
Diana

Hi,

How does it fail? What's the error?
