[PATCH 0/5] rbd: kill create_snap sysfs entry

[Alex Elder <elder@inktank.com>]

The point of this sixth series is as the subject indicates--to
get rid of the /sys/bus/rbd/create_snap entry.  There is no need
to provide this functionality via the kernel client, it is done
quite well using the user space "rbd" command.

Simply removing the functionality would leave rbd_req_sync_exec()
with no other references though, and we'll be making quite a bit
of use of that function in supporting format 2 rbd images.

So this series inserts a patch that adds another function we will
want that will make use of rbd_req_sync_exec(). And that patch
requires the other three as prerequisites as well--supporting
data returned from requests made via rbd_req_sync_exec(), then
using the function to perform new "image_id" retrieval operation
on a special image id file used for version 2 images.

It is available as branch "wip-rbd-review-6" on the ceph-client git
repository, and is based on the branch "wip-rbd-review-5".
