Summary: [PATCH] Evdev ioctls EVIOCGRAB and EVIOCREVOKE don't
work together with cuse

patch to change type of EVIOCGRAB and EVIOCREVOKE ioctls to _IO
EVIOCGRAB and EVIOCREVOKE from dev/evdev/input.h are defined as _IOWINT.
Those ioctls don't actually write an integer, though. What matters is the value
of the data pointer. Cuse, however, only passes along the value of the data
pointer when the length of the ioctl is 0 (see
https://github.com/freebsd/freebsd/blob/master/sys/fs/cuse/cuse.c#L1669).
One solution would be to define those two ioctls as _IO (see attached patch).
I've tested this with my cuse-based evdev implementation
(https://github.com/jiixyj/evdevfbsd).
