2009-07-14Input: fix EVIOCGNAME/JSIOCGNAME regressionDaniel Mack1-2/+1
Commit 3d5cb60e ("Input: simplify name handling for certain input handles") introduced a regression for the EVIOCGNAME/JSIOCGNAME ioctl. Before this, patch, the platform device's name was given back to userspace which was good to identify devices. After this patch, the device is ("event%d", minor) which is not descriptive at all. This fixes the behaviour by taking dev->name.

2009-06-20Input: synaptics - add support for reporting x/y resolutionTero Saarni1-3/+9
Synaptics uses anisotropic coordinate system. On some wide touchpads vertical resolution can be twice as high as horizontal which causes unequal sensitivity on x/y directions. Add support for reading the resolution with EVIOCGABS ioctl. Signed-off-by: Tero Saarni <tero.saarni@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2009-03-16Rationalize fasync return valuesJonathan Corbet1-4/+1
Most fasync implementations do something like: return fasync_helper(...); But fasync_helper() will return a positive value at times - a feature used in at least one place. Thus, a number of other drivers do: err = fasync_helper(...); if (err < 0) return err; return 0; In the interests of consistency and more concise code, it makes sense to map positive return values onto zero where ->fasync() is called.

2008-11-01saner FASYNC handling on file closeAl Viro1-1/+0
As it is, all instances of ->release() for files that have ->fasync() need to remember to evict file from fasync lists; forgetting that creates a hole and we actually have a bunch that *does* forget. So let's keep our lives simple - let __fput() check FASYNC in file->f_flags and call ->fasync() there if it's been set. And lose that crap in ->release() instances - leaving it there is still valid, but we don't have to bother anymore.

Force feedback upload of effects through the event device (ioctl EVIOCSFF) is not working in 32 bit applications running on 64-bit kernel due to the fact that struct ff_effect contains a pointer, resulting in the structure having different sizes in 64 and 32 bit programs and causing difference in ioctl numbers.

2008-04-01Input: make sure input interfaces pin parent input devicesDmitry Torokhov1-4/+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.

2008-03-31evdev: Release eventual input device grabs when getting disconnectedBjörn Steinbrink1-0/+3

2007-06-04Input: reduce raciness when input handlers disconnectDmitry Torokhov1-1/+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>

2006-07-19Input: implement new force feedback interfaceAnssi Hannula1-17/+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.

2006-06-23[PATCH] vfs: add lock owner argument to flush operationMiklos Szeredi1-1/+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.
