Sage Weil	8c6e9229fc	ceph: add LAZYIO ioctl to mark a file description for lazy consistency ... Allow an application to mark a file descriptor for lazy file consistency semantics, allowing buffered reads and writes when multiple clients are accessing the same file.

Sage Weil	33d4909ccc	ceph: allow preferred osd to be get/set via layout ioctl ... There is certainly no reason not to report this. The only real downside to allowing the user to set it is that you don't get default values by zeroing the layout struct (the default is -1).

Sage Weil	8f4e91dee2	ceph: ioctls ... A few Ceph ioctls for getting and setting file layout (striping) parameters, and learning the identity and network address of the OSD a given region of a file is stored on. Signed-off-by: Sage Weil <sage@newdream.net>	2009-10-06 11:31:14 -07:00
