In 2.2, you used to just be able to call functions "init_module" and "cleanup_module" and they'd be magically called. These days you should use module_init(myinit)/module_exit(myexit) and avoid #ifdef MODULE. Signed-off-by:

As noticed by Joey Hess (and thanks for Christoph for forwarding it). Also requirements from Werner Almesberger. If someone passes 'foo="some value"' the param engine removes the quotes and hands 'foo' and 'some value'. The __setup() parameters expect a single string, and so we try to regenerate it from the two parts. Finally, we try to place it as an environment variable. Werner wants quotes stripped out of the environment variable. It makes sense to do that for __setup, too (so it sees 'foo=some value'), since __setup functions don't usually handle quotes.

Currently, only module parameters in loaded modules are exported in /sys/modules/, while those of "modules" built into the kernel can be set by the kernel command line, but not read or set via sysfs. - move module parameters from /sys/modules/$(module_name)/$(parameter_name) to /sys/modules/$(module_name)/parameters/$(parameter_name) - remove dummy kernel_param for exporting refcnt, add "struct module *"-based attribute instead - also export module paramters for "modules" which are built into the kernel, so parameters are always accessible at /sys/modules/$(KBUILD_MODNAME)/$(parameter_name) Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (modified) Signed-off-by:

The session leader should disassociate from its controlling terminal and send SIGHUP signals only when the whole session leader process dies. Currently, this gets done when any thread in that process dies, which is wrong. This patch fixes it. Signed-off-by:

This patch changes process accounting to write just one record for a process with many NPTL threads, rather than one record for each thread. No record is written until the last thread exits. The process's record shows the cumulative time of all the threads that ever lived in that process (thread group). This seems like the clearly right thing and I assume it is what anyone using process accounting really would like to see. There is a race condition between multiple threads exiting at the same time to decide which one should write the accounting record. I couldn't think of anything clever using existing bookkeeping that would get this right, so I added another counter for this. (There may be some potential to clean up existing places that figure out how many non-zombie threads are in the group, now that this count is available.) Signed-off-by:

The current cursor interface is confusing. Some fields are taken from the cursor structure in struct fb_info (enable, mask, rop fields) and the rest are taken from the passed cursor structure. These lead to a lot of confusion, making it hard for developers to write their own implementation. Also, the cursor code has several 'short-circuits', occassionally leading to undefined cursor behavior. These are the changes brought about by the patch: - Removed struct fb_cursor and related fields from struct fb_info, and instead, placed them in a struct not visible to fbdev. - The struct fb_cursor passed to fb_cursor() will _always_ contain valid data with various bitflags indicating which fields have changed - The struct fb_pixmap sprite in struct fb_info is used only by drivers with hardware cursor implementation. Initializing and allocating memory for this structure is not needed. Remove initialization and memory allocation. - The FBIO_CURSOR ioctl is broken (because fb_cursor() is broken). For now, remove fb_cursor code and make the FBIO_CURSOR ioctl always return -ENODEV. - The flag FB_CUR_SETCUR is changed to FB_CUR_SETIMAGE, indicating that the cursor sprite has changed. The image change is now checked by fbcon so drivers will not unnecessarily load the sprite image everytime. This causes hardware cursors to flicker, especially in rivafb. - Remove fb_load_cursor_image(). This is unused, and should not be implemented generically. - Documented the usage of the cursor interface in skeletonfb.c Signed-off-by:

This patch adds a new IV mode ''encrypted sector|salt IV'' described in http://article.gmane.org/gmane.linux.kernel.device-mapper.dm-crypt/472 To use ESSIV, set the ivmode (using the new syntax) to "essiv:<hash>". "hash" should be a valid cryptoapi hash. This, for example, is a valid dm-target line: 0 200 crypt aes-cbc-essiv:sha256 00000000000000000000000000000000 0 /dev/loop/5 0 Signed-Off-By:

Create crypt_iv_operations structure with generator method and move the plain iv generator into this structure. Optionally accept an extended <sector format> syntax: <cipher>-<chaining mode>-<iv mode> This also makes it ready to support chaining modes other than CBC mode, such as CMC (not implemented in cryptoapi yet), The problems outlined by Adam J. Richter in http://article.gmane.org/gmane.linux.kernel.device-mapper.dm-crypt/454 would be fixed by switching to CMC chaining mode.

Change pagevec "nr" and "cold" back to "unsigned long", because <4 byte accesses can be slow on architectures < Pentium III (additional "data16" operand on instruction). This still honours the cacheline alignment, making the size of "pagevec" structure a power of two (either 64 or 128 bytes). Haven't been able to see any significant change on performance on my limited testing. Signed-off-by:

Newer versions of module-init-tools do some locking now which leads to a dead-lock if cpia.c does a request_module("cpia_usb/pp"). The attached patch against 2.6.8 removes the request_module. The problem is actually the same as is documented in debian bug #259056 which was caused by alsa autoloading some oss-modules. So I guess there might be more places in the kernel where this new locking in the module-init-tools might lead to dead-locks. Signed-off-by:Peter Pregler <Peter_Pregler@email.com> Acked-by:

Weak symbol may be unavailable in kernel, but if it is available, its signature should be same as was at the build time. If we do not attach signatures to weak symbols, kernel is tainted when such module is loaded. vmmon: no version for "sys_ioctl" found: kernel tainted. I also believe that it is safer to add & check signatures here - module wants either sys_ioctl with right signature, or no sys_ioctl at all, not sys_ioctl with different signature (which signals that there is some misbuild occuring).

Each md personality keeps a list of devices that are currently active in the array (mdk_rdev_t). As these can potentially be removed at any time, some locking is needed when accessing entries in the list. Currently this involves a spinlock, but all the spinlocking this imposed in unplug_slaves bothered me. So, I have changed it to use rcu locking. This is more appropriate as objects are removed only very rarely, and there is no cost in waiting a little while for a remove to succeed. Also, all changes to the list of devices are performed by the per-array thread (calling md_check_recovery) and so are completely single threaded, so no locking between writers is needed at all. Finally, devices are never added or removed while resync is happening, so resync doesn't need to worry about locking at all. So with this patch, the spinlocking is replaced with rcu read locking and synchronize_kernel. The rcu_read_lock is held while dereferencing a possible device, and the nr_pending count is atomically incremented if the device is to be held outside of the rcu_read_lock. When removing a device, if the nr_pending count appears to be zero, we set the list entry to NULL and call synchronize_kernel(). If the count is still zero after this, we have a safe removal. If it is non-zero, then someone has just started using it so we put the pointer back and fail the removal. When the new user finally drops it's reference, that will cause the per-array thread to wake up again and retry the removal. Signed-off-by:
