* Input: make sure input interfaces pin parent input devicesDmitry Torokhov2008-04-011-4/+2
| | | | | | | | | | Recent driver core change causes references to parent devices being dropped early, at device_del() time, as opposed to when all children are freed. This causes oops in evdev with grabbed devices. Take the reference to the parent input device ourselves to ensure that it stays around long enough. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
* evdev: Release eventual input device grabs when getting disconnectedBjörn Steinbrink2008-03-301-0/+3
| | | | | | | | | | | When getting disconnected we need to release eventual grabs on the underlying input device as we also release the input device itself. Otherwise, we would try to release the grab when the client that requested it closes its handle, accessing the input device which might already be freed.

* Input: Add proper locking when changing device's keymapDmitry Torokhov2008-01-211-3/+3

* get rid of input BIT* duplicate definesJiri Slaby2007-10-191-6/+6
| | | | | | | | | | | | | | | | | | | | | | get rid of input BIT* duplicate defines use newly global defined macros for input layer. Also remove includes of input.h from non-input sources only for BIT macro definiton. Define the macro temporarily in local manner, all those local definitons will be removed further in this patchset (to not break bisecting).

| * Input: reduce raciness when input handlers disconnectDmitry Torokhov2007-06-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a race between input handler's release() and disconnect() methods: when input handler disconnects it wakes up all regular users and then process to walk user list to wake up async. users. While disconnect() walks the list release() removes elements of the same list causing oopses. While this is not a substibute for proper locking we can reduce odds of getting an oops if we wake up normal readers after walking the list. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

* Input: implement new force feedback interfaceAnssi Hannula2006-07-191-17/+15
| | | | | | | | | | | | | | | | | 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.

* Input: introduce input_inject_event() functionDmitry Torokhov2006-07-061-3/+3
| | | | | | | | | | 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.

* [PATCH] vfs: add lock owner argument to flush operationMiklos Szeredi2006-06-231-1/+1
| | | | | | | | | | | | | | | | | | | Pass the POSIX lock owner ID to the flush operation. This is useful for filesystems which don't want to store any locking state in inode->i_flock but want to handle locking/unlocking POSIX locks internally. FUSE is one such filesystem but I think it possible that some network filesystems would need this also. Also add a flag to indicate that a POSIX locking request was generated by close(), so filesystems using the above feature won't send an extra locking request in this case.
