We don't need a "default" ktype for a kset. We should set this explicitly every time for each kset. This change is needed so that we can make ksets dynamic, and cleans up one of the odd, undocumented assumption that the kset/kobject/ktype model has. This patch is based on a lot of help from Kay Sievers. Nasty bug in the block code was found by Dave Young <hidave.darkstar@gmail.com> Cc: Kay Sievers <kay.sievers@vrfy.org> Cc: Dave Young <hidave.darkstar@gmail.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

Due to the change in kobject name handling, the module kobject needs to have a null release function to ensure that the name it previously set will be properly cleaned up. All of this wierdness goes away in 2.6.25 with the rework of the kobject name and cleanup logic, but this is required for 2.6.24. Thanks to Alexey Dobriyan for finding the problem, and to Kay Sievers for pointing out the simple way to fix it after I tried many complex ways.

Commit faf8c714 caused a regression: parameter names longer than MAX_KBUILD_MODNAME will now be rejected, although we just need to keep the module name part that short. This patch restores the old behaviour while still avoiding that memchr is called with its length parameter larger than the total string length.

sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded. For more info regarding lifetime rule cleanup, please read the following message. http://article.gmane.org/gmane.linux.kernel/510293 (tweaked by Greg to not delete the field just yet, to make it easier to merge things properly.)

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.

The parsing of some kernel parameters seem to enable irq's at a stage that irq's are not supposed to be enabled (Particularly the ide kernel parameters). Having irq's enabled before the irq controller is initialized might lead to a kernel panic. This patch only detects this behaviour and warns about wich parameter caused it.

Initialize module_subsys earlier (or at least earlier than devices) since it could be used very early in the boot process if kmod loads a module before the device initcalls. Otherwise, kmod will crash in kernel/module.c:mod_sysfs_setup() since the kset in module_subsys is not initialized yet. I only noticed this problem because occasionally, kmod loads the modules for my SCSI and Ethernet adapters very early, during the boot process itself. I don't quite understand why it loads them sometimes and doesn't load them other times. Or who is telling kmod to do so. Can someone explain?

The module files, refcnt, version, and srcversion did not properly increment the owner's module reference count, allowing the modules to be removed while the files were open, causing oopses.

I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

there seems to be a bug, at least for me, in kernel/param.c for arrays with .num == NULL. If .num == NULL, the function param_array_set() uses &.max for the call to param_array(), wich alters the .max value to the number of arguments. The result is, you can't set more array arguments as the last time you set the parameter. example: # a module 'example' with # static int array[10] = { 0, }; # module_param_array(array, int, NULL, 0644); $ insmod example.ko array=1,2,3 $ cat /sys/module/example/parameters/array 1,2,3 $ echo "4,3,2,1" > /sys/module/example/parameters/array $ dmesg | tail -n 1 kernel: array: can take only 3 arguments Signed-off-by: NBert Wesarg <wesarg@informatik.uni-halle.de> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
