[PATCH] driver core: fix built-in drivers sysfs links

2007-04-02T17:06:09+00:00

built-in drivers had broken sysfs links that caused bootup hangs for
certain driver unregistry sequences.

Revert "driver core: refcounting fix"

2007-03-09T23:25:04+00:00

This reverts commit 63ce18cfe685115ff8d341bae4c9204a79043cf0.

It was the incorrect fix and causes a reference counting bug whenever
any driver module is removed from the system. Mike Galbraith
 is looking for the real fix for his problem.

Revert "Driver core: let request_module() send a /sys/modules/kmod/-uevent"

2007-02-23T22:54:57+00:00

This reverts commit c353c3fb0700a3c17ea2b0237710a184232ccd7f.

It turns out that we end up with a loop trying to load the unix
module and calling netfilter to do that.  Will redo the patch
later to not have this loop.

driver core: refcounting fix

2007-02-23T22:52:09+00:00

Fix a reference counting bug exposed by commit
725522b5453dd680412f2b6463a988e4fd148757.  If driver.mod_name exists, we
take a reference in module_add_driver(), and never release it.  Undo that
reference in module_remove_driver().

Driver core: let request_module() send a /sys/modules/kmod/-uevent

2007-02-16T23:19:15+00:00

On recent systems, calls to /sbin/modprobe are handled by udev depending
on the kind of device the kernel has discovered. This patch creates an
uevent for the kernels internal request_module(), to let udev take control
over the request, instead of forking the binary directly by the kernel.
The direct execution of /sbin/modprobe can be disabled by setting:
  /sys/module/kmod/mod_request_helper (/proc/sys/kernel/modprobe)
to an empty string, the same way /proc/sys/kernel/hotplug is disabled on an
udev system.

Modules: only add drivers/ direcory if needed

This changes the module core to only create the drivers/ directory if we
are going to put something in it.
