* Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki2007-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

* Fix use-after-free oops in Bluetooth HID.David Woodhouse2007-07-07
| | | | | | | | | | | | | | | | When cleaning up HIDP sessions, we currently close the ACL connection before deregistering the input device. Closing the ACL connection schedules a workqueue to remove the associated objects from sysfs, but the input device still refers to them -- and if the workqueue happens to run before the input device removal, the kernel will oops when trying to look up PHYSDEVPATH for the removed input device. Fix this by deregistering the input device before closing the connections.

| * Bluetooth HID: HIDP - don't initialize force feedbackJiri Kosina2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | The current implementation of force feedback for HID devices is USB-transport only and therefore calling hid_ff_init() from hidp code is not going to work (plus it creates unwanted dependency of hidp on usbhid). Remove the hid_ff_init() until either the hid-ff is made transport-independent, or at least support for bluetooth transport is added.

|/ | | | | | | | | | | | In preparation for struct class_device -> struct device input core conversion, switch to using input_dev->dev.parent when specifying device position in sysfs tree. Also, do not access input_dev->private directly, use helpers and do not use kfree() on input device, use input_free_device() instead.

* [PATCH] bluetooth hid quirks: mightymouse quirkJiri Kosina2007-03-29
| | | | | | | | | | | | | | | | | | | I have a bugreport that scrollwheel of bluetooth version of apple mightymouse doesn't work. The USB version of mightymouse works, as there is a quirk for handling scrollwheel in hid/usbhid for it. Now that bluetooth git tree is hooked to generic hid layer, it could easily use the quirks which are already present in generic hid parser, hid-input, etc. Below is a simple patch against bluetooth git tree, which adds quirk handling to current bluetooth hidp code, and sets quirk flags for device 0x05ac/0x030c, which is the bluetooth version of the apple mightymouse.

* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

* [Bluetooth] Fix HID disconnect NULL pointer dereferenceMarcel Holtmann2006-10-20
| | | | | | | | | The latest HID disconnect sequence change introduced a NULL pointer dereference.

* [Bluetooth] Let BT_HIDP depend on INPUTMarcel Holtmann2006-07-12
| | | | | | | | | | | | | | | | | This patch lets BT_HIDP depend on instead of select INPUT. This fixes the following warning during an s390 build: net/bluetooth/hidp/Kconfig:4:warning: 'select' used by config symbol 'BT_HIDP' refer to undefined symbol 'INPUT' A dependency on INPUT also implies !S390 (and therefore makes the explicit dependency obsolete) since INPUT is not available on s390. The practical difference should be nearly zero, since INPUT is always set to y unless EMBEDDED=y (or S390=y).

* [NET]: move struct proto_ops to constEric Dumazet2006-01-03
| | | | | | | | | | | | | | | | | | | | | | I noticed that some of 'struct proto_ops' used in the kernel may share a cache line used by locks or other heavily modified data. (default linker alignement is 32 bytes, and L1_CACHE_LINE is 64 or 128 at least) This patch makes sure a 'struct proto_ops' can be declared as const, so that all cpus can share all parts of it without false sharing. This is not mandatory : a driver can still use a read/write structure if it needs to (and eventually a __read_mostly) I made a global stubstitute to change all existing occurences to make them const. This should reduce the possibility of false sharing on SMP, and speedup some socket system calls. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

* [NET]: Transform skb_queue_len() binary tests into skb_queue_empty()David S. Miller2005-07-08
| | | | | | | | | | | | | This is part of the grand scheme to eliminate the qlen member of skb_queue_head, and subsequently remove the 'list' member of sk_buff. Most users of skb_queue_len() want to know if the queue is empty or not, and that's trivially done with skb_queue_empty() which doesn't use the skb_queue_head->qlen member and instead uses the queue list emptyness as the test.

In 1.1.13 that need had disappeared, along with register_chrdev(SOCKET_MAJOR, "socket", &net_fops) in sock_init(). Include had not.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
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!
