always assign miscdevice to file->private_data

2015-03-23 Thread Martin Kepplinger
I've been trying this a few months ago, ( https://lkml.org/lkml/2014/10/8/98 ) in a very bad attempt that (thankfully) failed. I'm happy to see you trying this now and got the change in drivers/fuse merged now. I've been running a kernel with this change for quite some time, it's obviously fine.

[PATCH 1/3] misc: always assign miscdevice to file->private_data in open()

As of now, a miscdevice driver has to provide an implementation of the open() file operation if it wants to have misc_open() assign a pointer to struct miscdevice to file->private_data for other file operations to use (given the user calls open()). This leads to situations where a miscdevice
