Re: [Xen-devel] [PATCH] Add an ioctl interface for simple xenstore access

This patch adds an ioctl interface to /proc/xen/xenbus to allow simple

xenbus_read() support, but write, remove, etc could be easily added.
Also, this interface can be easily moved to /dev/xen/xenbus (or
something similar) later.

Hmm, wouldn't a virtual file system be a much better fit for xenstore
access? the kernel community considers ioctls Evil with a capital E.

Also, we already support xenstore access via read/write on that device file. And libxenstore knows how to target that read/write interface. Why would we add an ioctl to do the same thing?
