Clients can make use of these directories, and ceph-common is required by
ceph, so nothing should break here.
Change the purge postrm script to be for ceph-common (it does nothing else).

The older versions of ceph-common (ceph CLI, in particular) can't talk to
newer clusters. The primary change happened with dumpling when the new
CLI and rest-api changes were made. Although in reality ceph doesn't
care what version of ceph-common is installed, in practice this forces
ceph-common to get upgraded along with ceph and avoids some user pain.

Introduce XfsFileStoreBackend class, currently the only filestore
backend implementing SETALLOCHINT op. This commit adds a build-time
dependency on libxfs as xfs-specific ioctl (XFS_IOC_FSSETXATTR /
XFS_XFLAG_EXTSIZE) is used to implement the new set_alloc_hint()
method.

It loads a designated erasure-code plugin and calls its
methods. It is convenient to figure out and tune the number of data
chunks, the size of an aligned chunk etc. For instance:
ceph_erasure_code \
--parameter erasure-code-plugin=jerasure \
--parameter erasure-code-directory=.libs \
--parameter erasure-code-technique=reed_sol_van \
--parameter erasure-code-k=2 \
--parameter erasure-code-m=2 \
--all
displays the chunk size when encoding an object of 1024 bytes.
get_chunk_size(1024) 512
get_data_chunk_count 2

librados.hpp uses std::tr1::shared_ptr which may not be available such
as in libc++. This switches the use to ceph::shared_ptr and as a result
also ships include/memory.h for the definition.

Install the plugins in /usr/lib/ceph/erasure-code instead of
/usr/lib/erasure-code to comply with FHS : "Applications may use a
single subdirectory under /usr/lib."

The debian package is modified to install the plugins as part of the
ceph package which also ships rados-classes.

Upstart script for mapping / unmapping rbd device based on /etc/ceph/rbdmap file.
It does not mount or unmount filesystem, this part should be performed by _netdev option in fstab.
Signed-off-by: Laurent Barbe <laurent@ksperis.com>
Currently the way 'rbd unmap' translates a user-provided block device
into an rbd id is it matches the major number of the specified device
against /sys/bus/rbd/devices/<id>/major for each rbd mapping and
declares success on the first match. This works for both entire disks
and partitions, because under the current device number allocation
scheme, each mapping means a new major number.
In preparation for support for single-major device number allocation
scheme, which would require matching both major and minor numbers, make
sure to always match against entire disk device numbers, by converting
the specified device major:minor pair into wholdedisk major:minor pair.
To achive that, use the libblkid library, which accomplishes this goal
by walking stable sysfs structures.
