Re: [Xen-devel] [PATCH] [RFC] sysfs support for xen linux

My impression is was that sysfs files are mostly meant to be very simple get/set attributes and not have magic properties like the privcmd file - do
any other sysfs files even support ioctls().

Also, for things like privcmd() which are used to perform operations, isn't it
cleanest to make them a character device than a proc file?

Probably true, but then it's a pain either needing to create device files in /dev, or interface with the devfs/udev du jour. I suppose we already have that issue with /dev/xen/evtchn though, and creating the device node can be hidden in libxc.
