Description of problem:

This is tracker to follow https://bugzilla.kernel.org/show_bug.cgi?id=28682

I've managed to reach the 32 evdev devices limit on a big multi-seat system. Growing the system further is limited by this fact. Would love to see this fixed in Fedora and then backported to RHEL.

We've had a customer report this issue and have recreated it.

    Input: extend the number of event (and other) devices
    
    Extend the amount of character devices, such as eventX, mouseX and jsX,
    from a hard limit of 32 per input handler to about 1024 shared across
    all handlers.
    
    To be compatible with legacy installations input handlers will start
    creating char devices with minors in their legacy range, however once
    legacy range is exhausted they will start allocating minors from the
    dynamic range 256-1024.

v3.7 was the first kernel with this. Closing this.

Alexander, could you close the kernel.org BZ as well please?

thanks,
