[PATCH] [KERNEL-DOC] kill warnings when building mandocs

From: Borislav Petkov
Date: Fri Apr 13 2007 - 05:15:42 EST


This patch shuts warnings of the sort:

make -C /mnt/samsung_200/sam/kernel/trees/21-rc6/build \
KBUILD_SRC=/mnt/samsung_200/sam/kernel/trees/21-rc6 \
KBUILD_EXTMOD="" -f /mnt/samsung_200/sam/kernel/trees/21-rc6/Makefile mandocs
make -f /mnt/samsung_200/sam/kernel/trees/21-rc6/scripts/Makefile.build obj=scripts/basic
make -f /mnt/samsung_200/sam/kernel/trees/21-rc6/scripts/Makefile.build obj=Documentation/DocBook mandocs
SRCTREE=/mnt/samsung_200/sam/kernel/trees/21-rc6/ /mnt/samsung_200/sam/kernel/trees/21-rc6/build/scripts/basic/docproc doc /mnt/samsung_200/sam/kernel/trees/21-rc6/Documentation/DocBook/wanbook.tmpl >Documentation/DocBook/wanbook.xml
if grep -q refentry Documentation/DocBook/wanbook.xml; then xmlto man -m /mnt/samsung_200/sam/kernel/trees/21-rc6/Documentation/DocBook/stylesheet.xsl -o Documentation/DocBook/man Documentation/DocBook/wanbook.xml ; gzip -f Documentation/DocBook/man/*.9; fi
Note: meta version: No productnumber or alternative sppp_close
Note: meta version: No refmiscinfo@class=version sppp_close
Note: Writing sppp_close.9
Note: meta version: No productnumber or alternative sppp_open
Note: meta version: No refmiscinfo@class=version sppp_open

by adding a RefMiscInfo xml tag in the form of the current kernel version to
the function, struct and enum definitions in files included by kernel-doc when
building 'mandocs'. However, the version string appears truncated on the manpage
due to some constraints in the xml DTD for the man header, I believe, for the
troff output is truncated too.
