Subject: Re: [PATCH] RDMA/irdma: puda: Clear entries after allocation to
ensure clean state
Hi Wentao,
kernel test robot noticed the following build errors:
[auto build test ERROR on rdma/for-next]

[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use '--base' as documented in
