rbd: kill create_snap sysfs entry
Josh proposed the following change, and I don't think I could explain it any better than he did: From: Josh Durgin <josh.durgin@inktank.com> Date: Tue, 24 Jul 2012 14:22:11 -0700 To: ceph-devel <ceph-devel@vger.kernel.org> Message-ID: <500F1203.9050605@inktank.com> Right now the kernel still has one piece of rbd management duplicated from the rbd command line tool: snapshot creation. There's nothing special about snapshot creation that makes it advantageous to do from the kernel, so I'd like to remove the create_snap sysfs interface. That is, /sys/bus/rbd/devices/<id>/create_snap would be removed. Does anyone rely on the sysfs interface for creating rbd snapshots? If so, how hard would it be to replace with: rbd snap create pool/image@snap Is there any benefit to the sysfs interface that I'm missing? Josh This patch implements this proposal, removing the code that implements the "snap_create" sysfs interface for rbd images. As a result, quite a lot of other supporting code goes away.
