Thanks for the feedback Russell, we will further consider how to make this summary report more helpful, and reduce unnecessary distribution to many mailing list. Typically, 0day ci sends 2 kinds of reports, one is bisected report, which has specific warning/error as you mentioned to related receivers. Such as https://lore.kernel.org/all/202207130344.auqexe4e-...@intel.com/ The other is this summary, we want to give an overview to the owner for the head status. And we will re-consider the appropriate audiences for the mail and the contents to make it clear. > > Russell. > > On Thu, Jul 14, 2022 at 09:56:19AM +0800, kernel test robot wrote: > > tree/branch: > > https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master > > branch HEAD: 4662b7adea50bb62e993a67f611f3be625d3df0d Add linux-next > > specific files for 20220713 > > > > Error/Warning reports: > > > > https://lore.kernel.org/linux-doc/202207021352.ppktuy8v-...@intel.com > > https://lore.kernel.org/linux-doc/202207031437.qih6lfcx-...@intel.com > > https://lore.kernel.org/linux-doc/202207051821.3f0erisl-...@intel.com > > https://lore.kernel.org/linux-doc/202207140742.gtpk4u8i-...@intel.com > > https://lore.kernel.org/linux-mm/202206292052.lsfui3zo-...@intel.com > > https://lore.kernel.org/linux-mm/202207140042.ck3tlk6j-...@intel.com > > https://lore.kernel.org/llvm/202207090100.acxdj79h-...@intel.com > > > > Error/Warning: (recently discovered and may have been fixed) > > > > Documentation/PCI/endpoint/pci-vntb-function.rst:82: WARNING: Unexpected > > indentation. > > Documentation/PCI/endpoint/pci-vntb-howto.rst:131: WARNING: Title underline > > too short. > > Documentation/filesystems/netfs_library.rst:384: WARNING: Inline emphasis > > start-string without end-string. > > Documentation/filesystems/netfs_library:609: fs/netfs/buffered_read.c:318: > > WARNING: Inline emphasis start-string without end-string. > > Documentation/virt/kvm/api.rst:8256: WARNING: Title underline too short. > > Documentation/virt/kvm/api.rst:8263: WARNING: Unexpected indentation. > > drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc.c:2837:6: warning: no > > previous prototype for function 'dc_reset_state' [-Wmissing-prototypes] > > drivers/mmc/host/sdhci-of-aspeed-test.c:10: undefined reference to > > `kunit_binary_assert_format' > > drivers/pci/endpoint/functions/pci-epf-vntb.c:975:5: warning: no previous > > prototype for 'pci_read' [-Wmissing-prototypes] > > drivers/pci/endpoint/functions/pci-epf-vntb.c:984:5: warning: no previous > > prototype for 'pci_write' [-Wmissing-prototypes] > > drivers/vfio/vfio_iommu_type1.c:2141:35: warning: cast to smaller integer > > type 'enum iommu_cap' from 'void *' [-Wvoid-pointer-to-enum-cast] > > fs/ntfs/attrib.c:705:18: warning: Either the condition '!al' is redundant > > or there is pointer arithmetic with NULL pointer. > > [nullPointerArithmeticRedundantCheck] > > fs/ntfs/layout.h:126:43: warning: Parameter 'p' can be declared with const > > [constParameter] > > fs/ntfs/ntfs.h:144:3: warning: Assignment of function parameter has no > > effect outside the function.

Hi, I don't mean to discourge test systems, but looking at this, I just go "meh" and delete it - it doesn't seem to contain obviously useful information. One has to read every damn line to see if there's something of relevence, which I for one am not going to do. Is there some kind of improvement that could be done to this to make it more useful - such as only sending the warnings/errors to the appropriate mailing lists for those - rather than grouping everything together into one email. At least that should make the stuff (a) more relevant and (b) easier to parse. Russell.
