docs: merge debugging-modules.txt into sysctl/kernel.rst
This fits nicely in sysctl/kernel.rst, merge it (and rephrase it) instead of linking to it. Signed-off-by: Stephen Kitt <steve@sk2.org> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

-Debugging Modules after 2.6.3
------------------------------
-
-In almost all distributions, the kernel asks for modules which don't
-exist, such as "net-pf-10" or whatever. Changing "modprobe -q" to
-"succeed" in this case is hacky and breaks some setups, and also we
-want to know if it failed for the fallback code for old aliases in
-fs/char_dev.c, for example.
-
-In the past a debugging message which would fill people's logs was
-emitted. This debugging message has been removed. The correct way
-of debugging module problems is something like this:
-
-echo '#! /bin/sh' > /tmp/modprobe
-echo 'echo "$@" >> /tmp/modprobe.log' >> /tmp/modprobe
-echo 'exec /sbin/modprobe "$@"' >> /tmp/modprobe
-chmod a+x /tmp/modprobe
-echo /tmp/modprobe > /proc/sys/kernel/modprobe
-
-Note that the above applies only when the *kernel* is requesting
-that the module be loaded -- it won't have any effect if that module
-is being loaded explicitly using "modprobe" from userspace.
