Subject: Re: [PATCH V6] scsi: ufs: Add configfs support for UFS provisioning
Hi Sayali,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on mkp-scsi/for-next]
[also build test ERROR on v4.18-rc5 next-20180716]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
url: https://github.com/0day-ci/linux/commits/Sayali-Lokhande/scsi-ufs-Add-configfs-support-for-UFS-provisioning/20180716-212258
base: https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git for-next
config: ia64-allmodconfig (attached as .config)
compiler: ia64-linux-gcc (GCC) 8.1.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
GCC_VERSION=8.1.0 make.cross ARCH=ia64
