[PATCH 7/7] docbook: use IDs as filenames to support multiple books

[Randy Dunlap]

From: Johannes Berg <johannes.berg@intel.com>

I'm trying to generate a <set> of <book>s in
docbook for wireless to link together all the
cfg80211 and mac80211 documentation.

However, docbook will generate "re01.html"
anew for each book for the first <refentry>,
presumably due to a bug in the stylesheets.

An effective workaround is to use IDs for the
filenames, which makes them more descriptive
as well, e.g. API-enum-ieee80211-band.html.

[PATCH 3/7] Documentation: update kbuild loadable modules goals & examples

[Randy Dunlap]

From: matt mooney <mfm@muteddisk.com>

Update section 3.3 Loadable module goals - obj-m, from $(<module_name>-objs)
to $(<module_name>-y) for easier addition of conditional objects to the
module. The examples are also updated to reflect the current state of
each Makefile used.

[PATCH 1/7] aio: fix wrong subsystem comments

change, I confirmed the kernel applying this patch can boot on my i386 box.

Since I doesn't subscribe this list, please Cc me if you reply this mail.
