2007-02-18Input: do not lock device when showing name, phys and uniqDmitry Torokhov
Now that sysfs attributes return -ENODEV once driver requests their removal we do not need to handle scenario when data is deleted from under our feet and can simplify the code. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau
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).

2007-02-12[PATCH] mark struct file_operations const 3Arjan van de Ven
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2006-09-14Input: fix input module refcountingDmitry Torokhov
Now that input_free_device is basically an alias for input_put_device we need to acquire a reference to input module right when we allocate device because input_dev_release releases reference to input module unconditionally. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2006-07-19Input: implement new force feedback interfaceAnssi Hannula
Implement a new force feedback interface, in which all non-driver-specific operations are separated to a common module. This includes handling effect type validations, locking, etc. The effects are now file descriptor specific instead of the previous strange half-process half-fd specific behaviour. The effect memory of devices is not emptied if the root user opens and closes the device while another user is using effects. This is a minor change and most likely no force feedback aware programs are affected by this negatively. Otherwise the userspace interface is left unaltered.

2006-07-19Input: add missing handler->start() callDmitry Torokhov
The start() method need to be called every time we create a new handle. This includes not only registering new devices but also when registering new handlers. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2006-07-06Input: introduce input_inject_event() functionDmitry Torokhov
Create input_inject_event() function which is to be used by input handlers as opposed to input_event() which is reserved for drivers implementing input devices. The difference is that if device is "grabbed" by some process input_inject_event() will ignore events unless sent from the handle that is currently owns the device. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2006-07-06Input: add start() method to input handlersDmitry Torokhov
The new start() method is called immediately after connect() and also when "grabbed" device is released by its owner. This will allow input handlers to re-synchronize state of once-grabbed device with the rest of devices. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2006-06-27Input: fix resetting name, phys and uniq when unregistering deviceDmitry Torokhov

2006-06-26Input: reset name, phys and uniq when unregisteringDmitry Torokhov
Name, phys and uniq are quite often constant strings in moules implementing particular input device. If a module unregisters input device and then gets unloaded, the device could still be present in memory (pinned via sysfs), but aforementioned members would point to some random memory. Set them all to NULL when unregistering so sysfs handlers won't try dereferencing them. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2006-01-04[PATCH] Input: add modalias supportRusty Russell
Here's the patch for modalias support for input classes. It uses comma-separated numbers, and doesn't describe all the potential keys (no module currently cares, and that would make the strings huge). The changes to input.h are to move the definitions needed by file2alias outside __KERNEL__. I chose not to move those definitions to mod_devicetable.h, because there are so many that it might break compile of something else in the kernel. The rest is fairly straightforward.
