Hi all,

After merging the mm tree, today's linux-next build (htmldocs) produced
thess warnings:

/home/sfr/next/next/Documentation/ABI/testing/sysfs-class-bdi:76: ERROR: Unexpected indentation.
/home/sfr/next/next/Documentation/ABI/testing/sysfs-class-bdi:89: ERROR: Unexpected indentation.
/home/sfr/next/next/Documentation/ABI/testing/sysfs-class-bdi:48: ERROR: Unexpected indentation.

Introduced by commit

  93e6d447506d ("mm: document /sys/class/bdi/<bdi>/min_bytes knob")
  a0eef74439b2 ("mm: document /sys/class/bdi/<bdi>/max_ratio_fine knob")
  3aafa9ff1d4f ("mm: document /sys/class/bdi/<bdi>/min_ratio_fine knob")

[PATCH] mm: fix indentation of bdi sysfs description

[Bagas Sanjaya]

Stephen Rothwell reported htmldocs warnings when merging mm tree:

Documentation/ABI/testing/sysfs-class-bdi:76: WARNING: Unexpected indentation.
Documentation/ABI/testing/sysfs-class-bdi:89: WARNING: Unexpected indentation.
Documentation/ABI/testing/sysfs-class-bdi:48: WARNING: Unexpected indentation.

These warnings are due to inconsistent indentation in description of bdi
sysfs symbols.

Fix these by following indentation of surrounding text.

Perfect. I'll ignore similar reports with _noprof prototype warnings until then.

Those patches entered the mm tree after I had merge it on Thursday.  It
should all be good on Tuesday.

https://lore.kernel.org/all/20240327044649.9199-1-rdunlap@infradead.org/
which seems to not yet been pulled into mm-unstable should fix the
following warnings:

include/linux/slab.h:730: warning: Function parameter or struct member
'_n' not described in 'kcalloc'
include/linux/slab.h:730: warning: Function parameter or struct member
'_size' not described in 'kcalloc'
include/linux/slab.h:730: warning: Function parameter or struct member
'_flags' not described in 'kcalloc'
include/linux/slab.h:730: warning: Excess function parameter 'n'
description in 'kcalloc'
include/linux/slab.h:730: warning: Excess function parameter 'size'
description in 'kcalloc'
include/linux/slab.h:730: warning: Excess function parameter 'flags'
description in 'kcalloc'

And https://lore.kernel.org/all/20240326054149.2121-1-rdunlap@infradead.org/
should handle the _noprof warnings. I can see this patch in
mm-unstable and running "make htmldocs" in mm-unstable does not show
the _noprof warnings anymore. Please let me know if I should try some
other command to reproduce these.
Thanks,
Suren.

Thanks! I'll change back all the instances in the documentation where
we replaced original names with _noprof versions.

Thanks for the report, Stephen!
Let us check with Randy Dunlap how we should handle these. I assume we
still want documentation to document kmalloc(), not kmalloc_noprof().
Maybe there is a way to mute these warnings.

Please just keep it with the patch that exposed this situation i.e. in

I will send this as a separate patch to linuxppc-dev ? Even though the
warning started with this series because it is using functions in
meminit from remove_pte_table, marking remove_pte_table correctly is
applicable outside series that caused this warning ?

From 29ddcbbcae6ec2a7b70015274b2d5c4ec9b6beea Mon Sep 17 00:00:00 2001

Subject: [PATCH] powerpc/mm: Fix section mismatch warning

remove_pte_table is only called from remove_pmd_table which is marked
__meminit. These functions are used only during memory hotplug and they
also call functions marked __meminit. Mark remote_pte_table also with
__meminit so that we can avoid the section mismatch warning below.

Documentation/filesystems/proc.rst:1162: WARNING: Block quote ends without a blank line; unexpected unindent.
