Hi all,

After merging the ntb tree, today's linux-next build (htmldocs) produced
this warning:

Documentation/PCI/endpoint/pci-vntb-function.rst:82: WARNING: Unexpected indentation.
Documentation/PCI/endpoint/pci-vntb-howto.rst:131: WARNING: Title underline too short.

lspci Output at Host side

[PATCH 1/2] Documentation: PCI: Use code-block block for scratchpad registers diagram

[Bagas Sanjaya]

The diagram in "Scratchpad Registers" isn't formatted inside code block,
hence triggers indentation warning:

Documentation/PCI/endpoint/pci-vntb-function.rst:82: WARNING: Unexpected indentation.

Fix the warning by using code-block directive to format the diagram
inside code block, as in other diagrams in Documentation/. While at it,
unindent the preceeding text.

[PATCH 2/2] Documentation: PCI: extend subheading underline for "lspci output" section

[Bagas Sanjaya]

The underline syntax for "lspci output..." section is off-by-one less
than the section heading's length, hence triggers the warning:

Documentation/PCI/endpoint/pci-vntb-howto.rst:131: WARNING: Title underline too short.

Extend the underline by one to match the heading length.

commit 0539f970a8427138026d4738a7a32d869f1be300
Author: Masahiro Yamada <yamada.masahiro@socionext.com>
Date:   Thu Jul 11 14:44:31 2019 +0900

    kbuild: create *.mod with full directory path and remove MODVERDIR

is the first bad commit.


drivers/ntb/core.c defines MODULE_VERSION().

When CONFIG_DEBUG_SECTION_MISMATCH=y,
scripts/mod/sum.c tries to open the non-existing old
source based on the stale *.mod file
during the directory descending.


I will kill cmd_secanalysis for tomorrow's linux-next.


Thanks for catching various bugs!

But that was last changed in June, so I assume that some change to the
build system has caused this warning to be produced now.

I renamed the ntb.c file to core.c so we could add more files to build
ntb.ko. See [1].

linux-next: build warning after merge of the ntb tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 554 bytes --]

Hi all,

After merging the ntb tree, today's linux-next build (x86_64 allmodconfig)
produced this warning:

WARNING: could not open /home/sfr/next/next/drivers/ntb/ntb.c: No such file or directory

The only thing I could see that might be relevant is commit

  56dce8121e97 ("kbuild: split out *.mod out of {single,multi}-used-m rules")

and some others in the kbuild tree. Nothing has changed recently in the
ntb tree ...

drievrs/ntb builds a module called ntb but there is no ntb.c file.

Any ideas?
